I was born in the US but migrated to the Philippines when I was 5 years old. My documents were taken by my aunts who told us that they would take care of the documents. They told us they would take us back to the US before our 18th birthday. Both my parents are Filipino. And since then I've been living in the Philippines. The problem is we've been unable to contact my aunts, and my uncle who also has contact with them doesn't want to help us get our documents back. We haven't received anything from the US embassy (they say we should have support but I'm not sure about this). All of the documents are with my aunts except for my birth certificate. What is the best way that I can handle this. I'm 23 now. I hope someone can help me. Thank you.
If you are born to Philippine parents, you have Philippine citizenship, so there should be no problem with your current status in the Philippines.
If you have a US birth certificate, you should be ok for the US to. Contact the US embassy and apply for a passport. It's going to take a while and might involve a bit of back and forth. Since you were born in the US and have a US birth certificate you already ARE a US citizen. They will eventually issue you a passport.
Read up on dual citizenship in the Philippines. You may have to apply for this and since you are probably late for this already you should do it as soon as possible.
Forget your Aunts and Uncles. Ignore whatever documents they have or pretend to have.
