What documents do I need to submit for a single entry 60-day tourist e-visa application for Thailand?

For your first question, upload the receipt from your hotel that shows you paid. For your second question, I don't know where they're asking you to show proof of your work. Yes they ask but all they care about is if you have enough money in the bank, which yes, to prove, you should show your latest bank statement. Don't understand what you're asking for with your third question. Is a person inviting you to stay? Are you booking a hotel? Don't get what you're asking here. Document for current residency either needs to be your passport or your ID. Depends on the phrasing of the question and which country you're coming from. Give us the exact phrasing of the question and which country you're from and we can tell you.
