Wow. I've never come across a US citizen by birth taken back to Mexico where name and birth certificate was changed. Seems to me that many things need to done here. I recommend that you obtain your US birth certificate; hopefully, it shows that your parents are the same on both, US and Mexican birth certificate. You may also want to obtain a declaration from your mother stating what she did and why, and have it notarized. Most of all, you need to consult with an immigration attorney because your matter is complicated and may take a long time and legal fees/costs in proofing that you are indeed a US citizen by birth. If it is true and proved then you could petition your son and live in the US as a US citizen.
