You must be married to apply with a Cuban under CAA, assuming Cuban is qualified under CAA. Good luck.

Yes, you may change status and apply green card if married USC. You don't have to be in status to file.

USC 21 years or older may petition parents for US permanent residency.

What happens if I was never fingerprinted or booked in? What is your immigration question, issue, or concern?

Not a problem at all. Take sufficient ids to show ASC/USCIS officials you are the same person. Caution: chose the name you prefer to use and be...

For I90 it doesn't matter. USCIS is aware most people don't know. I would answer TSC in Mesquite.

Your question was channeled to immigration in error. I have tried to correct. Good luck.
