I know an applicant who was dependent in early 1990s when he came to the US with his father. His father had J1 visa and we're not sure if he had J2 visa (we do not know when J2 visa was first issued, we're not sure because H4 dependent visa was issued in 1997).
Now assuming back then the J2 visa was issued to dependents, the applicant in hand did not have a passport and was registered as dependent on his father's. He left the US mid 1990s and never returned.
He is now applying for a B1 visa and the application asks whether or not he had visa to the US previously. The application proceeds to ask for the date of the visa.
Unfortunately, they cannot find the date since it was over 20 years ago. They are not even sure if he had a J2 visa to begin with since he had no passport at the time.
Question #1: is it possible for him to find his dependent visa records provided that he had Social-Security-Number when he was in the US?
Question #2: if the answer to 1 is Yes, where can he get the information from? And what is the procedure to follow?
Question #3: if the answer to 1 is No, what date should be provided on the application form given he can't possibly get the records? And how does that affect his application?
