I find the idea of using an agency for these kind of things pretty hilarious though. You're paying money to simply upload documents to a different party, not saving you any time or effort.
my tenative plan is to stay in Thailand for June and July and then I'll be either in US or Vietnam after that. Will apply for DTV then. Can't figure out if I should use an agency. My remote work brings in $30K+/mo. I think I should be approved, but countries have been known to deny digital nomad Visas for people who are overqualified.
