Since you guys travels a lot, I imagine lots of preparation must be done.
FOr example, you get the Thailand DTV Visa, stay there for 6 months.
Then you get Vietnam e-visa, you stay there for 3 months.
Then you get some other visa, you stay in that country for 3 months.
Rinse / repeat.
Doesn't raise suspicion in terms of countries thinking you live there.
Could be a good video idea for newbies like myself.
