The N-560 certificate of citizenship, obtained by filing form N-600, is not needed in order to obtain a US passport, and a US passport is proof of US citizenship. Furthermore, a US passport can be renewed 9 times for the cost of a N-600. So, why would anyone need to apply for a Certificate of Citizenship?
I have seen some sources claim that it's needed to apply for federal student loans or security clearances. I haven't been able to validate either of these claims. For federal student loans, it seems that the certificate of citizenship is only needed in cases of derivation where the social security record for the student still indicates that they are an alien. However, this could be easily solved by bringing your US passport to the social security office to have them update the record. For security clearance, I looked at the SF-86 form and it seems that if you have a US passport, you don't have to submit a certificate of citizenship.
The only situation I can think of where someone would need a certificate of citizenship is when they're not allowed to get a US passport, for example because they are on probation or are behind on child support obligations. Are there any others?
