This is from the tourist eVisa form, see quote. Would uploading the first page of your passport do?
Quote: "9. Applicant must apply for e-Visa via specific Embassy/Consulate conforming with his/her consular jurisdiction and residency. Applicant is required to upload document that can verify his/her current residency."
And for how long do you need to have proof of (Airbnb) accommodation, any rules for that? Would 1 week be enough, eventhough I plan to stay for 60 days?
