Form I-129F, Explained: A Complete Guide by TRW Law Firm
Your Path to the K-1 and K-3 Visa for a Fiancé(e) or Spouse of a U.S. Citizen
What is Form I-129F?
Form I-129F, officially titled “Petition for Alien Fiancé(e),” is a foundational document used by U.S. citizens to bring their foreign fiancé(e) or spouse to the United States. It enables the foreign partner to apply for either:
🟩 A K-1 visa, allowing a fiancé(e) to enter the U.S. for marriage within 90 days
🟩 A K-3 visa, allowing a spouse to enter the U.S. while waiting for their immigrant visa
Although the K-3 visa is seldom used today due to faster adjustment-of-status alternatives, Form I-129F remains an essential immigration tool for international couples seeking to start their life together in the U.S.
At TRW Law Firm, we guide clients through every nuance of Form I-129F, ensuring legal compliance and minimizing delays.
Who Should Use Form I-129F?
You can file Form I-129F if:
🟩 You are a U.S. citizen (green card holders are not eligible to use this form).
🟩 You are engaged to a foreign national and plan to marry them in the U.S. within 90 days of their entry (K-1 visa).
🟩 OR, you are married to a foreign national and have already filed Form I-130 (K-3 visa, rarely used).
🟩 You have met your fiancé(e) in person within the past two years — unless you qualify for a waiver due to cultural or hardship reasons.
Who Cannot File Form I-129F?
🟥 U.S. green card holders (lawful permanent residents)
🟥 U.S. citizens who have not met their fiancé(e) in person in the past two years and cannot justify a waiver
🟥 Individuals without documentary proof of a bona fide relationship
🟥 Individuals filing for the purpose of convenience or fraud
If you fall into one of these categories, you may need to explore alternative routes to reunite with your loved one. Contact TRW Law Firm for tailored guidance.

Bringing a fiancé(e) to the U.S. is a multi-phase process. Here’s a general breakdown:

What Is the Processing Time for Form I-129F?
As of early 2025, the average USCIS processing time for Form I-129F is 6 to 8 months, though it may vary depending on workload, background checks, and completeness of your application.

Can You Expedite the Processing?
Unfortunately, premium processing is not available for Form I-129F. However, you may submit an expedite request through the USCIS Contact Center if you can provide compelling reasons (e.g., military deployment, urgent medical concerns, humanitarian grounds).
To qualify for expedited processing, your request must meet at least one of the following criteria:
🟩 Severe financial loss to a company or person
🟩 Emergency or urgent humanitarian reasons
🟩 USCIS error
🟩 Nonprofit organization interests (specific contexts)
🟩 U.S. government interests (e.g., public safety)
Requests are considered case-by-case. Documentation is crucial.

🟨 Filing fee waived for K-3 applications
🟨 No biometric fee required for I-129F
🟨 K-1 visa application and medical exam will incur additional fees later (at the embassy stage)

FAQs About Form I-129F
Can I file I-129F for a same-sex fiancé(e)?
✅ Yes. The U.S. government treats same-sex and opposite-sex petitions equally.
What if I haven’t met my fiancé(e) in person in 2 years?
You may apply for a waiver if it violates cultural or religious customs or causes extreme hardship. These waivers are rarely approved without strong documentation.
Do I need a lawyer to file I-129F?
Not required, but highly recommended — especially if you have prior immigration denials, criminal history, or complex family situations. TRW ensures compliance and reduces delays.
How can I track my petition?
Use your USCIS case receipt number on the USCIS Case Status portal.
Will USCIS interview the petitioner?
Not usually at the I-129F stage. Interviews typically occur at the consular stage (K-1 visa interview abroad) and during the adjustment of status process (green card interview).
Can a green card holder file I-129F?
🟥 No. Only U.S. citizens may file this form. Green card holders should file Form I-130 instead.
