I would say simply:
1. VPN - An absolute must
2. 13a - Save yourself some serious hassle and do it stateside.
4. Google Voice - A US number, and it receives text authentications. It has worked for NFCU, IRS, Schwab, Vanguard, Nationwide, SS, and others for me. I have only had one issue with a service spitting back that they don't take VOIP phone numbers. It was non-financial and a non-essential service.
5. Need a physical address in the US. A mailing service works, but a non-commercial address is better. Be careful on address though. Some financial companies withhold state taxes based on your address. That is a problem if you lived in no income tax state and used a taxed state address of a relative.
6. Take Flicks' Philhealth recommendation
7. Police clearance - Might want to check with the consulate to see if it needs an apostille. That is an extra layer of hassle.
8. Money transfer - Use any service you like, but refer to No. 1. Use a VPN so it looks like you are initiating from the US. Never tell them or indicate that you live overseas.
On the VPN, it can be placed on both your computer and a phone. On the phone to allow you to do mobile banking and other services if you are more of a phone guy than a computer guy. It can also be placed on an android tv box so you can watch US Netflix and/or Amazon. Philippine Netflix has a more limited library. VPN is also mandatory if you wander the darker outskirts of the internet looking for movies and TV programs.
