My b1/b2 visa expired in march 2021. I has only traveled twice once for a week and once for 10 days in 10 year duration. I have got an appointment for match 2022 for renewal. Earlier I got visa on behalf of my company for attending the meeting. Now I have requested for tourism. What all should I take care of? I have no intentions to live in US but visiting friend in 2022. Thank you!!!
