I recently became US citizen and now planning to file for green card for my own parents from India. However, in past my parents overstayed on their visitor visa(6 months) in UK from 2002 to 2013. They applied for asylum in 2006 and case was going on but then they withdrew their file and then they were sent on their emergency passports(as their old passports were lost and expired, they were given white passport) to India. They had no other criminal activity there and also have No Objection Certificate from Police department of the city they were staying in UK. Now they have their new passports printed from India.

I wanted to know that Does any of this situations in past makes it difficult for them to obtain permanent residency in USA?

1. My son is currently a student studying engineering at a 4 year public college in Illinois. I am working in the US on H1B, and my son is on H4. The issue is that he turns 21 next year before he would finish his final year in college, and since would age out of the H4 So what are the options he has left to continue his study Can he change to F1?<br>

2. What are the caveats to this? Can he do the adjustment of status in the US, or does he need to travel out of the country? I've heard that F1 visa processing takes a long time to process, and there is no determinate time - he has about 14 months for him to become 21 years as of now. When inquired the college said they are not processing the I-20s for Fall 2021 now, only for Spring 2021, and have asked him to wait, what are the consequences of this ?
