Hi, i have a question about the non imm O visa which i have got through now, just been filling out the TDAC and its asking for my departure flight details. i am not exactly sure when im leaving, obviously before my 90 days are up, but it could be a fair bit sooner as i want to go to Japan too. so i have not got an onward flight.

Also at the end it says travellers need to have who approved vaccines ? its asking for which countries you have been to within the last 2 weeks and is not accepting GBR ?
Answer summary
The Non-Immigrant O visa application allows flexibility in filling out the TDAC. Departure flight details are not mandatory, so you can leave those fields blank. Concerning vaccination questions, these apply mainly if you've traveled from countries with yellow fever, and countries like GBR may not be accepted for that question.

The vaccination question is only if you've visited a country with yellow fever.

Departure details are not mandatory fields. Leave them blank. Indeed don’t even click in the boxes otherwise they’ll become mandatory.
