The issue is the DOB on the passport and visa of my mother. Both dates are different. On visa 21/9 and on passport 21/7. We found out now on her second travel to the US. On her first travel, she was not asked any questions and we were not even aware of it but now she was not allowed to board. What is the possible solution to get this corrected in the right way?
The first step is to correct passport and then reapply visa with correct date.
