I read somewhere on the internet that when a LPR marries a non resident and they file I-130 after 3 years the non-resident spouse can obtain a nonimmigrant V-1 status for 2 years (while waiting for the green card).

I called the INS and I was told it only applies if one got married and filed the I-130 before 2000.

How does it really work???

I have noticed that this board serves more of the need of USC rather than LPRs, hence the non or low interest responses to LPR related questions.

Anyway, you are right, V1 visa only applies to couples who have been married for 3 years + and have filled their I-130 before Dec 2000.

Fortunately, I fall into this category and should be due for one by Nov this year.
