Planning about a year into the future, there are things to take care of:
Passport: It needs to be valid through six months after your return date. Do you have enough blank pages left?
ATMs: Get a bank account that reimburses foreign ATM withdrawals. Charles Schwab.
Figure out who/how bills will be paid while you are gone.
Get a VPN.
A credit card that doesn’t charge foreign transaction fees.
Global Access.
Visas: Where are you planning on going that require Visa? How much time does it take to get one.
….to be continued.
