Thanks for this and other interesting and informative thread about U.S. Passport Renewal ^

I plan to renew mine in about two weeks at the quasi-embassy known as AIT (American Institute in Taiwan) in Taipei and this bring up my question:

I am a dual-citizen (U.S. and Taiwan) and still posses my TW passport which I use to exit and reenter Taiwan while I use my US one at my destination (to bypass visa requirements)

My question is this: Can I renewal my US passport in a third country I travel to frequently, such as Hong Kong, and take advantage of whatever expedited service at a 'real' US Embassy/Consulate that is not available here in TW even thou I don't reside there? Will I dig myself a proverbial hole with any dual-citizen issue associated with this decision?

Many thanks ahead for all the answers tips!
