The issue is that Boston would not confirm that a Certificate of Citizenship was acceptable. They would ONLY accept a Birth Certificate or Naturalization Certificate. Ngo could obtain neither.
The funny thing is when just talking with him, he said the PD was angry that they were sued instead of "filing a complaint". As if a lone person filing a complaint would have changed the department's stupid policy.
The people he talked to when trying to even apply were ignorant about even the idea that derivative citizenship even existed and never gave straight answers. Kinda glad he decided to call a week after to confirm if the Certificate of citizenship was really acceptable. After that i told him to ask on these forums and contact Comm2a.
