Alien Registration Number on I-130 if previously in USA on F-1 OPT?

[SnakeBite 3]

Hi,

This site has already been a huge help as I try to quickly prepare the I-130 as a result of an unexpected job opportunity and move back to the US with my non-US citizen spouse. Have a couple of question I haven't quite seen answered. Would be very grateful if anyone has any ideas.

My wife did grad school in the US on an F-1 visa and after graduating worked on OPT for a year in 2005. Based on my reading here and elsewhere, it seems that she may have had an Alien Registration Number then. She doesn't remember the number, is not sure whether the OPT card may be buried at her parents' house in her home country, and can't find any documentation related to it. Her email account from the time is gone, and there's no backup.

1. Is the Alien Registration number she had then still valid for documents or did it expire as soon as OPT expired?

2. If we don't know the number can we put N/A under Alien Registration number wherever it is asked? We do have her Social Security number and will put that on all forms.

3. Should we attach an explanation, also explaining that she no longer has the OPT card from 10 years ago? Or is it better to not write anything and not make things more complicated than needed?

Thanks!

1) She can certainly put that down if she has it, if not, don't worry.

2) unknown would be a more appropriate answer as the question is applicable. (n/a means not applicable)

3) I wouldn't worry about it.
