Ummm, actually it is. My niece was born in Indonesia in 1976 when my BIL was working for Hughes. She has a long form Indonesian BC. When her parents came back to the US in 1977, she was issued a COLB and a passport.
Now, 32 years later, she just got another passport and she only provided her COLB and that old passport. The COLB doesn't even list her parents but she recieved her brand new passport in record time just a few weeks ago.
Her parents registered her birth with the US Embassy, which issued her a US government birth cert. The Indonesian BC doesn't matter.
When her parents came back to the US in 1977, she was issued a COLB and a passport.
She had been issued a US Passport before she left Indonesia. You don't get a passport after arriving in the U.S., you must have it already to be admitted.
Now, 32 years later, she just got another passport and she only provided her COLB and that old passport.
The old U.S. passport is the proof of U.S. citizenship she needed to obtain a new passport. The COLB was irrelevant.
The COLB doesn't even list her parents but she received her brand new passport in record time just a few weeks ago.
She'd proved U.S. citizenship via an old passport, so unless the application form was messed up it should only take a few weeks. Days if you pay extra.
