Whats the difference between a K-1 visa and forms 129F?

Question

or are they the same thing? how long does it take?

do i have to fill in a G-325A aswell? what is an alien regestration number?

Answer 1

K-1 is a fiance/fiancee visa.

I-129F is an application form for the K-1 visa.

Yes, you have to file the G-325.

An alien registration number is what you get when you are issued a green card.
