Indian students currently working in the United States on OPT or STEM OPT who plan to travel home this summer face a visa risk that most are not planning for: if your F-1 visa stamp has expired, you cannot re-enter the US without obtaining a new one in India — and with no dropbox option available for F-1 renewals, every applicant must attend a mandatory in-person interview. According to the US State Department's Global Visa Wait Times portal (last updated April 15, 2026), F/M/J visa interview wait times at Indian consulates now range from 1 month in New Delhi and Chennai to 3.5 months in Kolkata — the longest of any Indian post. With over 1.43 lakh Indian students currently on OPT, and summer travel plans forming now, the window to book safely is closing fast.

Why OPT Travel to India Requires a Valid F-1 Visa Stamp
OPT is a work authorisation — not a visa. It allows F-1 graduates to work in the US for up to 12 months (or 36 months for STEM graduates), but it does not grant re-entry rights on its own. To re-enter the US after international travel, an OPT holder needs three documents: a valid F-1 visa stamp in their passport, a valid EAD (Employment Authorisation Document) card, and a travel-endorsed I-20 signed by their DSO within the last six months.
The critical issue for summer 2026: many Indian students who began their F-1 journey in 2022 or 2023 are now holding expired visa stamps. F-1 visas issued to Indian students are typically valid for 5 years. A student who received their visa in 2021 or 2022 may find it expired — or expiring — before their planned summer travel. An expired stamp means a mandatory visa interview in India before they can return to the US.
Before 2025, some F-1 renewal applicants could use the dropbox (interview waiver) process — submitting documents without attending an interview. That option no longer exists for F-1 visa holders. Under the State Department's updated interview waiver policy (effective October 1, 2025), interview waivers apply only to B-1/B-2 visitor visa renewals and H-2A agricultural worker visas. F-1, F-2, J-1, and M-1 applicants — every student and OPT holder — must attend an in-person interview, no exceptions.
| Before October 1, 2025 | From October 1, 2025 |
|---|---|
| Some F-1 renewals eligible for dropbox (interview waiver) under prior policy | All F-1 applicants require mandatory in-person interview — no dropbox available |
| Age-based exemptions existed (under 14, over 79) | Age-based exemptions removed — all ages require interview |
| 48-month renewal window for B-1/B-2 dropbox | 12-month renewal window for B-1/B-2 dropbox only — F-1 not included |

Current F-1 Wait Times at Every Indian Consulate — April 2026
The State Department updates its Global Visa Wait Times portal monthly. The April 15, 2026 data shows a significant divergence across Indian consulates — with Kolkata now carrying the heaviest backlog of any post in India.
| Consulate | F/M/J Next Available Appointment | What This Means for Summer Travel |
|---|---|---|
| New Delhi | 1 month | Book now for a May/June interview; manageable for July return |
| Chennai | 1 month | Book now for a May/June interview; manageable for July return |
| Mumbai | 2.5 months | Book immediately — a May booking gives a late-July interview, cutting it close |
| Hyderabad | 2.5 months | Book immediately — same risk as Mumbai; delay past May = August interview |
| Kolkata | 3.5 months | Highest wait in India — a May booking gives an August/September interview; summer return at serious risk |
Wait times are for next available F/M/J interview appointment.
Kolkata's 3.5-month wait is the sharpest concern. Students from West Bengal, Bihar, Jharkhand, Odisha, and the Northeast who default to the Kolkata consulate face the longest queue in the country. A student who books in late April is looking at an interview in mid-to-late August — after most US universities resume for the Fall semester. Missing the return date while on OPT carries serious consequences: OPT employment authorisation requires maintaining valid F-1 status, and an extended absence can jeopardise both.

Who Is Most at Risk This Summer
Not every OPT holder travelling to India needs a new visa stamp. The risk is specific to students whose F-1 visa has expired or will expire before their planned return date. Here is how to assess your situation:
You need a new F-1 stamp if: your current F-1 visa stamp has expired, or will expire before your planned return date to the US. An expired stamp means you cannot board a US-bound flight — airlines check visa validity at check-in.
You do not need a new stamp if: your F-1 visa stamp is still valid on your planned return date. You can re-enter on a valid stamp even if your OPT EAD was issued after the stamp date, provided you carry your EAD card and a travel-endorsed I-20.
The cohort most exposed: Indian students who received their F-1 visa in 2020 or 2021 — when many consulates issued 5-year visas — are now approaching or past expiry. Students who began their US degree in Fall 2021 and are now in their second or third year of STEM OPT are the highest-risk group. Many in this cohort have not travelled internationally since arriving in the US and may not have checked their stamp expiry date recently.
STEM OPT holders face additional complexity. If you are on a STEM OPT extension and your F-1 stamp expires while you are in India, you must obtain a new stamp before returning. The interview will assess your current status — STEM OPT, employer, and EAD details must all be consistent and documented. A gap in employment during STEM OPT, or an employer change not yet reflected in your SEVIS record, can complicate the interview.
What OPT Holders Travelling to India This Summer Must Do Now
Check your F-1 visa stamp expiry date today. Open your passport and find your F-1 visa stamp. Note the expiry date. If it expires before your planned return to the US, you need a new stamp. Do not assume your OPT EAD or I-20 validity covers re-entry — they do not replace an expired visa stamp.
Book your consulate appointment before you book your flights. This is the most important sequencing decision. Check current wait times at travel.state.gov and book your F/M/J interview appointment at ustraveldocs.com before committing to travel dates. Your return flight must be after your interview date — and after any post-interview administrative processing, which can add 3–10 business days.
If you are in the Kolkata consulate zone, consider applying at New Delhi or Chennai. You are not required to apply at the consulate nearest to your home address. New Delhi and Chennai currently show 1-month waits versus Kolkata's 3.5 months. If you can travel to Delhi or Chennai for your interview, the time saving is significant. Confirm the consulate's current wait time before booking — times update monthly.
Prepare your complete document set before the interview. For an F-1 renewal on OPT, you will need: valid passport, DS-160 confirmation, SEVIS fee receipt (I-901), current EAD card, travel-endorsed I-20 (signed by DSO within 6 months), offer letter or employment verification from your current employer, pay stubs for the last 3 months, and a letter from your employer confirming your OPT employment. Incomplete documentation is the most common cause of administrative processing delays.
Build in a 2-week administrative processing buffer. Even after a successful interview, F-1 visas can be placed in administrative processing — a security review that typically takes 3–10 business days but can extend to several weeks. Do not plan to return to the US within 2 weeks of your interview date. For Kolkata applicants, the combined wait time (3.5 months to interview + 2-week buffer) means a May booking may not result in a safe return until September.
Do not travel if your OPT end date is within 3 months. If your OPT or STEM OPT expires within 3 months of your planned travel, the risk of being stranded in India — due to visa delays or administrative processing — is too high. Consult your university's international student office before booking any travel in the final quarter of your OPT period.

A Summer With No Margin for Error
The combination of mandatory interviews, rising wait times, and a tightening immigration environment makes summer 2026 the most complex travel season for Indian OPT holders in recent memory. The 1.43 lakh Indian students currently on OPT represent the largest cohort of Indian professionals in the US pipeline — the group most likely to convert F-1 status into H-1B sponsorship and long-term US careers. A stranded visa applicant in Kolkata is not just a travel inconvenience. It is a gap in OPT employment that can affect H-1B eligibility, a missed project deadline, and in some cases, a jeopardised job offer.
The consulate data is updated monthly. The window to act safely — booking an interview that clears before August — is open now for New Delhi and Chennai applicants, narrowing for Mumbai and Hyderabad, and effectively closed for Kolkata unless students act this week. Check your stamp, check the wait times, and book before you book your flight.
