K-1 Visa Processing Time: I-129F to Interview
A stage-by-stage view of the K-1 fiancé(e) visa in 2026 — filing Form I-129F, the National Visa Center handoff, the embassy interview, and what happens after entry. Ranges below are typical observed windows, not commitments. USCIS, the National Visa Center, the embassy, or the consular officer may request additional information at any point.
Written from official U.S. government sources. Last reviewed August 2026. Sources and limits.
At a glance
- I-129F petition (USCIS): the longest stage. Check the published range for your service center on the USCIS case processing times page.
- NVC transfer: roughly a few weeks to route the approved petition to the embassy or consulate serving your fiancé(e).
- Embassy interview: scheduling depends heavily on the post; medical exam and DS-160 come first.
- End to end: many couples observe a 12–18 month window from filing to visa in hand, then a further adjustment-of-status period after marriage.
The stages, in order
Official factOrigin: official source. Official sourceStated by a US government publisher on the page we cite.Sources for this page
1. File Form I-129F with USCIS
USCIS · Day 0The U.S. citizen petitioner files Form I-129F, Petition for Alien Fiancé(e). A receipt notice (Form I-797C) usually follows within a few weeks and establishes your case number. Only U.S. citizens may petition for a K-1.
2. USCIS adjudicates the petition
USCIS · Longest stageUSCIS reviews the petition and the evidence that you met in person within the two years before filing and intend to marry within 90 days of entry. Use the official USCIS case processing times page for the current range at your service center — it moves. A Request for Evidence pauses the clock while you respond.
3. Approved petition moves to the NVC
NVC · WeeksAfter approval, the case is forwarded to the National Visa Center, which assigns a case number and sends it on to the U.S. embassy or consulate with jurisdiction over your fiancé(e)'s residence.
4. Embassy packet, DS-160, and medical exam
You and the post · WeeksYour fiancé(e) completes Form DS-160, gathers civil documents, and attends a medical exam with an embassy-approved panel physician. Requirements and document formats are post-specific — follow the instructions from your embassy, not a generic checklist.
5. Consular interview
Embassy · Varies by postInterview availability differs dramatically between embassies. The consular officer decides the case; some cases go into 221(g) administrative processing afterward, which adds weeks to months.
6. Entry, marriage, and adjustment of status
USCIS · 90 days, then I-485The K-1 visa allows a single entry within six months of issuance. The couple must marry within 90 days of admission, after which the K-1 holder files Form I-485 to adjust status to lawful permanent resident — its own separate processing period.
K-1 versus CR-1: what the timeline really is
Togetherward analysisOrigin: Togetherward explanation. Togetherward explanationOur reading of the official sources, not something an agency says.
The K-1 often reaches the interview earlier than a CR-1 spouse visa, which is why it looks faster in side-by-side comparisons. But the K-1 does not end at entry: your fiancé(e) arrives without work authorization or permanent residence, and the adjustment-of-status filing that follows the wedding adds months before a green card is issued. A CR-1 arrives as a resident. Compare the full path, not the first milestone — our K-1 vs CR-1 guide walks through both.
What actually moves the timeline
Togetherward analysis- A complete initial petition. Clear evidence of meeting in person and of a genuine relationship is the most common way to avoid a multi-month Request for Evidence.
- Prompt responses. Every day a request sits unanswered is a day the case does not move.
- Your embassy. Interview wait times are post-specific and largely outside your control. Check the wait times published for your post.
- Administrative processing. A minority of cases receive 221(g) follow-up after the interview.
Why published K-1 estimates disagree with each other
Togetherward analysisTwo pages can both be honest and still print very different K-1 numbers, because they are rarely measuring the same thing. Before comparing any two figures, check four things about each one: which stage it covers, which cases it counted (the cohort), when it was observed (the window), and what it left out.
USCIS case processing times
- Stage it covers
- Form I-129F adjudication only, at one service center
- Cohort and window
- Completed cases USCIS reports for a recent period; the published range is a percentile view of that group, not an average of live cases
- What it excludes
- NVC transfer, embassy scheduling, the interview, entry, and the later adjustment-of-status filing
Department of State appointment wait times
- Stage it covers
- Interview appointment availability at one post
- Cohort and window
- Current scheduling capacity at that post, refreshed by the Department of State
- What it excludes
- Everything before the case reaches the post, and anything after the interview, including 221(g) administrative processing
End-to-end figures on advice sites and forums
- Stage it covers
- Usually filing to visa in hand, sometimes filing to green card
- Cohort and window
- Self-selected couples who chose to report, often across different service centers, posts, and years
- What it excludes
- Cases that never reported back, cases still pending, and any case that received a Request for Evidence or administrative processing
What each kind of published K-1 figure actually measures
| Figure | Stage it covers | Cohort and window | What it excludes |
|---|---|---|---|
| USCIS case processing times | Form I-129F adjudication only, at one service center | Completed cases USCIS reports for a recent period; the published range is a percentile view of that group, not an average of live cases | NVC transfer, embassy scheduling, the interview, entry, and the later adjustment-of-status filing |
| Department of State appointment wait times | Interview appointment availability at one post | Current scheduling capacity at that post, refreshed by the Department of State | Everything before the case reaches the post, and anything after the interview, including 221(g) administrative processing |
| End-to-end figures on advice sites and forums | Usually filing to visa in hand, sometimes filing to green card | Self-selected couples who chose to report, often across different service centers, posts, and years | Cases that never reported back, cases still pending, and any case that received a Request for Evidence or administrative processing |
- Different stages. A USCIS petition figure and an embassy wait figure are not comparable and cannot simply be added together into a total for your case.
- Different cohorts. Official figures describe cases that finished. Community totals describe couples who chose to post. Neither cohort is your case.
- Different observation windows. A figure read in January and a figure read now can both be accurate for their moment; the older one is not wrong, it is stale.
- Different exclusions. Most published figures quietly exclude Requests for Evidence, 221(g) administrative processing, and any case still pending, which pulls the number down.
- Different definitions of the finish line. “K-1 timeline” sometimes stops at the interview, sometimes at entry, and sometimes at the green card after adjustment of status.
The practical answer is to stop looking for one number. Read the current official figure for the stage your case is actually in, treat community totals as observations from other people's cases, and treat any single end-to-end number — including the observed window at the top of this page — as history rather than a schedule. We do not publish a remaining-time estimate for an individual case, and no source on this list can produce one.
Where to check current numbers
Official factOrigin: official source. Official sourceStated by a US government publisher on the page we cite.Sources for this page
Processing ranges, fees, and form editions change. Verify against the official sources rather than any static page — including this one: the USCIS case processing times tool for I-129F and I-485, and the Department of State visa appointment wait times page for your embassy.
Figures that change
These numbers change without notice. We only show one when a person has verified it against the official source recently enough; otherwise we say so and send you to the source.

Common questions
- How long does the K-1 visa take in 2026?
- Most K-1 fiancé cases run about 12 to 18 months from filing Form I-129F to the consular interview, combining USCIS adjudication, National Visa Center transfer, and embassy scheduling. USCIS publishes current I-129F ranges on its case processing times page, and wait times differ by embassy.
- How long does USCIS take to approve Form I-129F?
- I-129F adjudication is the longest single stage. Check the current published range for your service center on the USCIS case processing times page; a Request for Evidence typically adds several months.
- Is the K-1 visa faster than a CR-1 spouse visa?
- The K-1 often reaches the interview sooner, but it does not end at entry. The K-1 holder must marry within 90 days and then file for adjustment of status, which adds its own processing period before a green card is issued.
- Why do published K-1 processing time estimates disagree?
- Because they measure different things. USCIS publishes a figure for Form I-129F adjudication at one service center, the Department of State publishes appointment wait times for one post, and end-to-end figures on other sites come from self-selected couples across different centers, posts, and years. Each uses its own cohort, observation window, and exclusions, so the numbers are not comparable and cannot be added together into a total for an individual case.
- What happens after the K-1 visa is issued?
- The K-1 visa is valid for six months for a single entry. After admission, the couple must marry within 90 days, and the K-1 holder then files Form I-485 to adjust status to lawful permanent resident.

How we put this page together
Togetherward analysisWe took the published K-1 stage sequence — USCIS petition, National Visa Center transfer, consular processing, entry, and adjustment of status — and described each stage by the office that owns it and the official page that publishes its current figure. Observed end-to-end windows reflect what couples commonly report and are labelled as observations rather than official data, reviewed on the date shown.
What we did not include
- Any single end-to-end number presented as an estimate for an individual case.
- Current USCIS processing figures and embassy wait times, which move; we point at the official tools instead of copying them.
- Fees and form editions.
- Post-specific document requirements, which come from your embassy's own instructions.
