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.
