I-129F Case Tracker & Status Guide

Track your K-1 fiancé(e) petition from receipt to approval and consulate transfer.

Form I-129F — K-1 Fiancé Visa Petition. Track your K-1 fiancé(e) petition from receipt to approval and consulate transfer. The public tracker only shows your latest milestone; the internal USCIS API exposes the full sequence, including silent updates the website hides.

What is Form I-129F?

Form I-129F, Petition for Alien Fiancé(e), starts the K-1 fiancé visa process, letting a U.S. citizen bring their fiancé(e) to the United States to marry within 90 days of arrival.

After USCIS approval, the case moves to the National Visa Center and then the U.S. consulate abroad — transitions the internal API records as transfer events.

The I-129F milestone sequence

Behind each plain-English status the public site shows, USCIS records an internal event code. Here is the typical I-129F ladder and the codes that drive it:

IAFCase Was ReceivedReceipt notice issued.
FTA0Case Is Being Actively ReviewedAdjudication in progress.

How long does I-129F take?

I-129F processing at USCIS is only the first leg; NVC and consular interview stages follow. Watch for the approval and transfer events.
