Fingerprints2 years in a row in July I had my fingerprints done for my I-485. I know that they are valid for 15 months only. This year I didnt get anything. My case has not been approved yet. I had my interview back in October 2005. I made an infopass appointment, which is gonna be in 2 weeks just to check if I have to be fingerprinted again, but for now I would like to hear your opinion.
go and ask. and while you are there, get an idea about your case.
