U.S. Embassy Manila handles citizenship services for the whole Philippines; the Consular Agency in Cebu serves the Visayas. Both now use the electronic CRBA system.
If you go the immigrant-visa route, the required medical exam is done by a panel physician — in Manila that’s typically St. Luke’s Medical Center. The same facility is used for embassy-directed DNA collection.
Order Philippine civil records online from PSAHelpline.ph or PSASerbilis — no need to travel to a PSA office.
Immigrant-visa interviews (after the NVC stage) are also handled at U.S. Embassy Manila. See the Manila post page.
Addresses, hours, emails, and procedures change. Confirm on the official ph.usembassy.gov pages and your appointment confirmation before going. Bring valid ID; security screening applies.
