PhD Funding Offers and Your F-1 Visa: The Year-Six Gap
This happens a lot. The National Center for Science and Engineering Statistics (NCSES) reports a median of 5.7 years from the start of the doctoral program to the degree for 2023 US doctorate recipients, counting from master's entry when the master's was at the same institution in the same field (NCSES, Survey of Earned Doctorates, Table 1-12). That's a median among people who finished, so roughly half took longer. It varies by field: 5.3 years in engineering, 5.0 in business and 6.8 in humanities and arts (NCSES).
The Question Vault notes that guaranteed years and median completion time rarely match, and that the gap is when students teach extra sections or work outside the department to finish (The Question Vault). NYU Stern's PhD FAQ says the degree typically takes five to six years, and says funding is guaranteed for five, provided you stay in good standing (NYU Stern PhD FAQ). Duke's Graduate School generally guarantees five years of stipend, tuition and fees, plus six years of health and dental premiums.
In year six the stipend is up to each program, though Duke says tuition and fees are covered if the student tries to get support from the department or an outside source, and a sixth-year tuition and fee scholarship exists for those who apply and don't get it (Duke Graduate School). Missouri's accountancy PhD commits to four years and says it provides no support after year five under any circumstances (University of Missouri, School of Accountancy).
The offer letter covers the funding clock. A second clock, your I-20, runs under different rules and different offices.
Two clocks, two offices
Your department or graduate school controls the funding clock. Your university's international office controls the I-20 clock, and the designated school official (DSO) there sets and adjusts your program end date without needing federal approval (Inside Higher Ed).
Nobody checks year six when you arrive. To issue your first I-20, schools generally need proof of funds for one year. USC says its financial statement only has to cover first-year expenses, and ASU says the funding listed on the I-20 is only for the first nine months (USC Graduate Admission; ASU I-20 FAQs). The check comes when the I-20 needs extending.
Cornell requires F-1 students to show funds for tuition and living for the extension period or a year, whichever is shorter, and says federal regulations require a compelling academic or medical reason for the extension, such as a change of research topic, unexpected research problems or documented illness (Cornell International Services).
UF requires proof of financial support to extend an I-20, and says a graduate student on an appointment counts as fully funded at a stipend of at least $26,207 a year, with other proof of funds required if the appointment falls short (UF International Center; its figures rest on 2024/25 estimates). The New School says students may also be required to submit financial documents to extend (New School ISSS).
If the four-year rule comes back
A DHS rule capping F-1 admission at the program length or four years, whichever is shorter, was blocked nationwide by a preliminary injunction on September 14, and the government appealed to the First Circuit on September 30 (Federal Register; NAFSA). Fragomen told clients to prepare for a possible reversal and quick implementation with little or no notice (Fragomen). The checks in this piece hold under either outcome.
What the rule would change for a student in year six: anyone needing longer than the four years (plus 30 days) would file an extension of stay with USCIS (Mintz). DHS says a DSO's program extension and a USCIS extension of stay are different things, and that officers could use the process to verify, among other things, that applicants have the funds needed to live and study in the United States (Federal Register).
The rule lists three acceptable reasons: compelling academic reasons, medical reasons, or exceptional circumstances beyond the student's control (Inside Higher Ed). USCIS's fee schedule lists the general Form I-539 filing fee at $420 online or $470 on paper (USCIS Form G-1055), though the rule's process could change the form or fee. Mintz adds that with a fixed end date, staying past it without a timely extension application would start unlawful presence.
Reading an offer letter line by line
Split "guaranteed" into its parts. Stipend, tuition, fees and insurance can each run for a different length. Duke's numbers show it: five years of stipend, tuition and fees, six years of insurance premiums (Duke Graduate School). Ask for the written terms and not the number someone said at a visit day.
Then read the conditions. Missouri's package depends on satisfactory performance evaluated semester by semester, and bars substantive outside employment (University of Missouri, School of Accountancy). NYU Stern's guarantee depends on good standing.
Identify what kind of money it is. Duke's population health PhD, for example, funds students through research assistantships that require 19.9 hours a week (Duke Population Health Sciences FAQ). ProFellow, drawing on a survey of four international graduate students, notes that some federal grants can be earmarked for US citizens, and that an RA offer can fall through when a professor missed how those grant rules treat international students (ProFellow). A fellowship and a grant-funded RA slot fail in different ways, so know which one yours is.
Last, find the sentence about what happens after the final funded year. If the letter doesn't have one, treat that as information.
Same gap, two outcomes
This is an illustration, not an account of real people.
Picture two international students in the same department whose stipends end in the same month. Both need one more year to finish, and both go to the international office, which asks for proof of funds before it will extend the I-20.
The first has an email from the director of graduate studies, sent before she accepted, saying finishing students can request a teaching appointment. She forwards it, gets the appointment letter, and takes that to the international office. The second remembers a hallway conversation, so she's negotiating from memory.
What to ask, in writing, and who to ask
Funding questions go to the director of graduate studies (DGS). Duke tells applicants to ask the DGS because departments vary on support beyond the guarantee (Duke Graduate School). The Question Vault suggests asking the graduate coordinator about rules such as funding mechanics and what happens after the guaranteed years. I-20 questions go to the international office.
Four questions are worth sending before you accept:
- To the DGS: how many years does funding actually cover, and what happens after that? That's the first question in The Question Vault's list. Ask specifically about stipend, tuition and health insurance in year six, and who decides.
- To the DGS: how long do students in this department take from entry to defense? The Question Vault advises asking for the median for the last several cohorts, since departmental averages are often quoted from a good year or from the fastest subfield.
- To the international office: if my I-20 needs extending in year six, what funding proof do you require, and does a departmental assistantship count? UF publishes a specific dollar threshold, so ask your school for its own.
- To the DGS: if the fixed-period rule comes back, who pays the extension fee? A graduate workers' union at the University of Minnesota lists covering extension costs among demands it says the university hasn't met (Minnesota Daily, September 29, 2026).
Get the answers by email and keep them. My position: a vague answer to the first question is an answer. I'd weigh it as heavily as the headline stipend.
The question that gets missed
This is an illustration, not an account of a real person.
Imagine an admitted student who reads "five years guaranteed" in her offer letter and assumes her I-20 reflects the same five years. The letter belongs to her department and the I-20 belongs to the international office, and nothing forces the two to be compared until she needs an extension. The question she'd want to have asked is short: "After year one, what funding do you need to see from me, and will my department's letter count?" It takes one email, and the answer is on file before she has any money at stake.
What a gap year means in dollars
Two kinds of numbers show up: amounts you must show, and amounts you must pay. They vary by school, so treat these as examples.
Amounts to show: UMBC's proof-of-funds estimate for a new graduate I-20 is $52,643 for one year, a Spring 2027 figure, and UMBC notes the I-20 is not a bill (UMBC ISSS). UF says a one-year graduate extension requires showing at least $57,555, based on 2024/25 estimates, unless the student is on a qualifying appointment (UF International Center).
Amounts to pay: Yale doesn't treat year seven as automatic, and it needs program approval. Students are charged a Continuous Registration Fee each term, which the Graduate School covers in terms when the student teaches through its Teaching Fellow Program (Yale GSAS). At Duke, tuition and fees from year seven onward come from external funding, the department or the student, depending on the program (Duke Graduate School). If the rule returns, add the Form I-539 filing fee.
Shorter guarantee, better safety net?
I don't think one answer fits every field, but I do follow a rule. If the typical degree in my field outlasts both guarantees, the guarantee length stops being the deciding factor, so I take the clearer year-six policy. If the typical degree fits inside the longer guarantee but not the shorter one, I take the longer guarantee.
Field matters here. NCSES puts the humanities and arts median at 6.8 years, so even a six-year guarantee falls short. Use the department's median rather than a university-wide figure (The Question Vault).
Then check the advisor. In lab fields, your pay may come from one professor's grant, and some federal grants are earmarked for US citizens (ProFellow). A long departmental guarantee means little if your stipend depends on a grant that might end, so I'd ask who pays me in year five and what happens if that money stops.
Funding a final year
This is an illustration, not an account of a real person.
Imagine a fifth-year student whose assistantship ends after year five. In the fall, not the spring, he asks the director of graduate studies about teaching assignments for the next year, and he gets the answer by email. A teaching appointment gives him something to show the international office, and his savings cover any difference between the appointment and what the office requires. Asking in the fall left the department room to say yes.
What to do this week
Pull out each offer letter and find the last funded term for stipend, tuition and insurance separately. Email the DGS the year-six question and the median-time question. Find your target school's I-20 extension page, read what funding it requires, and email the international office the extension question. Then check the NAFSA litigation page for news on the First Circuit appeal. Save every written answer in one folder.
