I scheduled us tourist visa appointment for my mom and dad. While scheduling the appointment I had given the same DS 160 number for my mom and dad. I had paid the visa fees and scheduled the interview. When I look at the visa appoinmt letter I have the same ds160 for my mom and dad but have different bank receipt numbers. Later I noticed I had to fill a separate ds160 for my mom and I got the new confirmation#. My mom and dad had completed the finger print scanning yesterday and they did not mention anything. Will there be problem with the visa interview. How do I get the ds160 confirmation # corrected in the appointment letter.
