I was approved for my OPT on February 2008 for a duration of one year. At that time, I was allowed to stay in US for 1 year while looking for job. On April, 2008, a new regulation came according to which a student on OPT can not stay in US without job for more than 90 days. I was not aware of this rule until end of September 2008. Now I have applied for dependent visa. My worry is that unknowingly I stayed for around 6 month without job when I was actually allowed for only three month. I am worried that is this mistake going to affect my new visa approval? Is there anyway I can explain USCIS that it happened because I was not informed about this rule and I did not come across it.
Your best bet is to get your dependent visa stamp from a consulate as soon as possible. That should take care of any potential future problems.
