It would be best if you had a valid passport, bank statements from the last six months, and at least two valid photos. All of these should be looked over. Only the visa process system should be able to scan the documents. If any of the documents are left out, the user should get them checked. After the documents have been checked, a special stamp is put on each to show that the scanning process is done.
If you're going with someone else, you should have a return ticket for yourself. Both of you should have a return ticket that matches the end date of your Visa.

If they need to travel this way because of an emergency, they should get a note from their doctor.
