What Is a Postdoc in the US? Pay, Length and Visa Options for International PhDs

A postdoc is a paid, temporary research job after your PhD, and the visa attached to it decides how long you can stay, whether your spouse can work and how you reach a green card.

What is a postdoc? It is a temporary, paid research job you take after finishing a PhD, working under a faculty mentor to publish and build the independence that faculty, industry and government research roles expect. It is a job, not a degree. For an international PhD, the visa attached to it matters as much as the job. As of November 1, 2026, the three usual routes are all in effect: a J-1 research scholar program (up to five years), a cap-exempt H-1B from the university (no lottery), or F-1 OPT straight after the PhD. The rule that would have ended duration of status (D/S) for F-1 and J-1 holders is blocked by a federal court.

ItemStatus (as of 2026-11-01)What it means for a postdoc
D/S final ruleBlocked since 2026-09-14; summary judgment briefed; DHS appeal pendingF-1 and J-1 stay on D/S; the F-1 60-day grace period applies
OPT fee NPRM ($70,000 initial, $30,000 each later recommendation)Proposed; comments close 2026-11-09Not law; the school would be the legal payer, and only DSO recommendations dated 60+ days after a final rule would be covered
State Department J-1 NPRM on termination, extension and reinstatement (91 FR 48021)Proposed (2026-07-30); comment period closed; no final ruleCurrent J-1 rules apply
"Reforming the H-1B Nonimmigrant Visa Classification Program" (RIN 1615-AD00)Under OIRA review since 2026-08-24; no public textIts agenda abstract mentions "revising eligibility for cap exemptions"; nothing has changed
Florida and Texas public-university H-1B freezesIn effect (Florida 2026-03-02 to at least 2027-01-05; Texas 2026-01-27 to 2027-05-31)A new offer there may not come with a new H-1B

What is a postdoc? The short answer

A postdoc is a fixed-term research appointment for someone who already holds a doctorate. You are paid a salary or stipend to do research under a principal investigator (PI) as training for an independent career, and it is not a degree. International postdocs in the US usually work in one of three statuses: a J-1 research scholar program, a cap-exempt H-1B or F-1 OPT.

What does a postdoc actually do?

You run a research project and turn it into papers: experiments or analysis, first-author writing, grant drafts with your PI, mentoring graduate students and sometimes teaching.

Titles vary (postdoctoral researcher, scholar, fellow, research associate), and the title is not your status. Whether you are a payroll employee or a stipend-paid fellow changes benefits, tax withholding and which visa the international office can use, so ask HR before you sign.

Postdoc vs PhD: what changes the day you graduate

PhD studentPostdoc
What it isA degree programA job or funded fellowship after the degree
PayStipend, often with tuition supportSalary or stipend, no tuition
Usual statusF-1 or J-1 studentJ-1 research scholar, H-1B, or F-1 OPT
Who handles your statusYour school's DSO (F-1) or responsible officer (J-1)The employer's international scholar office; your DSO still handles OPT

After the PhD, F-1 covers postdoc work only through OPT, and the F-1 60-day grace period still applies because the D/S rule is blocked. On its Form I-539 page (updated 2026-10-07), USCIS says DHS "is preliminarily enjoined from taking any further action to implement the final rule" and "USCIS will proceed under the previous regulatory provisions."

How long is a postdoc in the US?

No federal rule sets a postdoc's length. Your institution's policy and your funding set the appointment, often renewed a year at a time, and your visa usually sets the hard ceiling.

StatusTime limit (as of 2026-11)Source
J-1 professor or research scholarUp to five years, counted continuously from the program start in SEVIS; then a two-year bar on returning in that category, separate from 212(e)22 CFR 62.20(i)
J-1 student academic training after a doctorateUp to 36 months in total, including earlier J-1 academic training, and never longer than your US course of study22 CFR 62.23(f)(4)(iii)
H-1BUp to 3 years at a time, 6 in total, longer in some green card situationsUSCIS H-1B page
F-1 OPT12 months per higher degree level, plus 24 months of STEM OPT if eligible8 CFR 214.2(f)(10); USCIS STEM OPT page

Our comparison of J-1 vs H-1B for researchers and postdocs explains the 212(e) home residency rule, and if you did your PhD as a J-1 student, J-1 academic training vs OPT covers the 36-month option.

What does a postdoc pay?

There is no federal postdoc salary. Your institution sets pay, and your visa adds its own floor.

Tax shifts with status. As a nonresident on F-1 OPT, the student FICA exemption generally applies; it ends when you change to a non-exempt status such as H-1B or become a resident alien, per the IRS foreign-student FICA page. Treaty articles for teachers and researchers differ by country, so take the offer to a tax professional who handles nonresident returns.

J-1 vs cap-exempt H-1B vs OPT: which visa comes with a postdoc?

The employer usually picks, but know what each choice means before you accept.

The J-1 research scholar route

A J-1 needs no USCIS petition, but check INA 212(e) before you accept. Under 8 U.S.C. 1182(e), the two-year home residency rule covers J-1s whose program was funded by the US or home government, nationals or residents of a Skills List country in their field, and graduate medical trainees. Until they spend two years at home or get a waiver, they cannot get an immigrant visa, permanent residence or an H or L visa, and under 8 U.S.C. 1258(a)(3) they cannot change status inside the US except to A or G. The 2024-12-09 Skills List removed China and India (and Saudi Arabia, South Korea and the UAE), but funding still triggers 212(e); our J-1 research scholar guide goes deeper.

J-1 applicants interview in person, so check the Global Visa Wait Times page, not anecdotes. The DOL Office of Inspector General also announced subpoenas on 2026-10-09 to nine universities over alleged J-1 misclassification; no findings had been published as of 2026-10-28.

The H-1B visa for a postdoc: the cap-exempt route

USCIS says H-1B workers "employed at an institution of higher education or its affiliated or related nonprofit entities, a nonprofit research organization, or a government research organization, are not subject to this numerical cap." A university can file any time of year, and under 8 CFR 214.2(h)(16)(i) an H-1B worker may "lawfully seek to become a permanent resident."

Three cautions. Florida's Board of Governors paused new H-1B hires at its 12 public universities, and Texas froze new petitions at state agencies and public universities, per the Texas Tribune; private employers are outside both. The $100,000 H-1B payment (first imposed in 2025, extended by Proclamation 11069 to 2027-09-21) is in effect on paper, but court orders now on appeal block its collection (as of 2026-11-01), and it never covered change-of-status or extension requests USCIS grants inside the US. Even so, initial consular H-1B petitions from cap-exempt employers fell 91% in the fee's first eight months, per CRS Insight IN12747 (2026-10-14). And cap exemption belongs to the employer, so a later company job may mean the lottery, as our postdoc-to-industry visa guide explains.

Can I do a postdoc on OPT?

Yes. Post-completion OPT covers work directly related to your major, and you get 12 months at each higher degree level under 8 CFR 214.2(f)(10), so master's OPT does not use up your PhD year. You can start work only once the EAD is approved and its start date arrives.

Per USCIS's OPT page, you "may apply up to 90 days before you complete your degree, but no later than 60 days after," and within 30 days of your DSO's SEVIS recommendation. The USCIS processing-times tool showed 80% of I-765 (c)(3) F-1 student cases completed within 5 months (read 2026-11-01). STEM OPT later needs an E-Verify employer and a Form I-983 training plan. The proposed OPT fee is not law.

The cap-gap trap when OPT turns into a university H-1B

Cap-exempt H-1B petitions get no cap-gap extension; the USCIS cap-gap page describes it only for cap-subject petitions. A pending university H-1B does not let you keep working once your OPT EAD ends: unless the H-1B is approved and starting by then, or you filed a timely STEM OPT extension, work stops. See whether cap-gap applies to cap-exempt H-1Bs for the timing.

A worked timeline: December 2026 PhD, March 2027 postdoc

Suppose your program end date is Friday, 2026-12-18, and a private university offers a postdoc starting 2027-03-01 on your OPT, with a cap-exempt H-1B to follow. Rules and tool figures are as of 2026-11-01; the dates are our arithmetic.

DateWhat happensRule or source
2026-11-02You file the OPT I-765 after your DSO's recommendation, asking for an OPT start date of 2027-02-16; if it takes the full 5 months the tool showed for 80% of cases, the decision comes around early April 2027Processing tool
2027-02-16Last day to file OPT, latest OPT start date you can request (both 60 days after program end) and end of the 60-day F-1 grace period; ask your DSO how a pending OPT application affects your stayUSCIS OPT page; SEVIS Help Hub
2027-03-01Planned job start, possible only if the EAD is approved by then (OPT premium processing, $1,780, runs on a 30-business-day clock); the 13 days since the EAD start count toward the 90-day unemployment limitG-1055
2027-08-16Earliest filing for an H-1B starting 2028-02-16: no H petition may be filed "earlier than 6 months before the date of actual need"8 CFR 214.2(h)(2)(i)(J)
2028-02-1512-month OPT EAD ends; without an approved H-1B or a timely STEM OPT filing, work stopsNo cap-gap for cap-exempt

The squeeze is in the last rows. The tool showed 10 months for an H-1B change of status (80% of cases, read 2026-11-01), but the petition can go in only six months early, so premium processing ($2,965, 15 business days) or a timely STEM OPT extension, which extends work authorization for up to 180 days while pending, often decides whether the plan holds. A J-1 offer instead means Form I-539 inside the US (8.5 months at 80%; premium $2,075) or a J-1 visa interview abroad.

Does a postdoc help with a green card?

Yes, mostly as evidence rather than as a sponsor. A postdoc produces the papers, citations and independent expert letters that EB-1A and EB-2 national interest waiver (NIW) self-petitions rely on. The postdoc job itself rarely supports EB-1B: under 8 CFR 204.5(i)(2), "Permanent, in reference to a research position, means either tenured, tenure-track, or for a term of indefinite or unlimited duration." The USCIS EB-1 page also asks for international recognition and at least three years of teaching or research; see our EB-1B outstanding researcher guide.

For calibration, USCIS I-140 data for FY2026 Q3 (April to June 2026; approvals over approvals plus denials) shows NIW at 55.3%, EB-1A at 32.2% and EB-1B at 93.0%. All of it predates PA-2026-05, in effect since 2026-08-05 and challenged in court, which lets officers deny without an RFE when required initial evidence is missing.

November 2026 Visa Bulletin Final Action Dates: EB-1 India 2023-02-01, China 2023-08-01, rest of world Current; EB-2 India 2013-11-01, China 2021-10-01, rest of world 2025-04-01. USCIS requires the Dates for Filing chart for November I-485s (filing charts), consular cases always use Final Action Dates, and the December bulletin is not out.

Status shapes the path. F-1 and J-1 both require "a residence in a foreign country which he has no intention of abandoning" under 8 U.S.C. 1101(a)(15), so raise any immigrant petition filed during either with an immigration attorney first. H-1B allows dual intent.

How to check a postdoc offer's visa plan before you sign

  1. Ask the PI and the university's international scholar office which status the job uses: J-1 (DS-2019), H-1B (Form I-129) or your own OPT (Form I-765).
  2. Ask HR whether it is a payroll position or a stipend-paid fellowship, and get the salary basis in writing.
  3. Confirm your program end date and OPT filing window with your current DSO before you agree a start date.
  4. Ask the international office when it will file Form I-129 relative to your OPT EAD end date and whether premium processing (Form I-907) is planned, then check the USCIS processing-times tool for I-765 (c)(3) and I-129.
  5. Review any DS-2019 with an immigration attorney for 212(e) triggers: government funding, a Skills List country and field, or graduate medical training.

Common mistakes

Frequently asked questions

Is a postdoc a degree?

No. A postdoc is a temporary, paid research appointment after a PhD, not a degree program, so it ends with publications and references rather than a diploma. As of November 2026 most international postdocs work on OPT, a J-1 research scholar program or an H-1B.

How long is a postdoc in the US?

No federal rule sets the length; institutions do, often renewing a year at a time. As of November 2026 your visa usually sets the ceiling, up to five years as a J-1 research scholar, six years on H-1B, or 12 months of OPT plus 24 months of STEM OPT.

What visa do international postdocs use, J-1 or H-1B?

Both are common, and new PhD graduates often start on F-1 OPT. A university can sponsor a J-1 research scholar with a DS-2019 or file a cap-exempt H-1B that skips the lottery. A J-1 can carry the 212(e) two-year home residency rule, while the H-1B allows dual intent.

Can I do a postdoc on OPT?

Yes, if the work relates directly to your PhD field and your EAD is approved before you start. USCIS lets you apply from 90 days before to 60 days after you complete your degree; its tool showed 80% of F-1 student I-765s decided within 5 months as of November 1, 2026.

Does a postdoc help with a green card?

Indirectly. Its publications, citations and expert letters are the evidence behind EB-1A and EB-2 NIW self-petitions, but a fixed-term postdoc is usually not the permanent research position EB-1B requires. A J-1 subject to 212(e) cannot get a green card until the rule is met or waived.

How we checked this: we read the USCIS, eCFR, State Department, ICE, IRS, Federal Register and CRS pages and the statute text linked above on November 1 and 2, 2026, and every status label is dated as of 2026-11-01.

This is general information, not legal or tax advice. Your own I-20, DS-2019, I-94 and approval notices govern; take F-1 and OPT questions to your DSO, J-1 program questions to your sponsor's responsible officer, petitions and status strategy to a licensed immigration attorney, and tax questions to a tax professional who handles nonresident returns.
