1. Yes. It has been answered. Numerous times.
2. No. You can do it yourself by mail from Taiwan. You can do it yourself by mail while in the US. You can have someone else assist you with the paperwork shuffle, but you need to provide your own fingerprints and signed application request form.

Lastly, the APRC requires an FBI background check, no other police background checks (State, Municiple) will suffice as of August 15, 2008. The only office which can authenticate the FBI background check is the TECRO office in Washington DC, which is the main US office in charge of all the other lower unit TECOs.
