yep, i was under the impression that it was a court order, but it was not, is a power of attorney. but i summited that to them at the time of the application. i hope they dont feel like i was lying to them. but i looking at the required documents from the page i posted from the usa embassy they never require all of this stuff? is it because im already in the usa? they wanted to know if i ever received well-fare but how could i since i didnt have a social security number. plus my dad had a good job and never had any of his kids on that.
The reason they ask for a court document has nothing to do with the fact that you are already in the U.S. The nationality laws are pretty complicated, and sometimes consulates and embassies do not post all the details regarding what is required. But, ultimately, in deciding if you are a citizen, the State Department has to go by what the law says.
The relevant section if INA to your case is § 309(a) INA, see
http://www.uscis.gov/ilink/docView/SLB/HTML/SLB/0-0-0-1/0-0-0-29/0-0-0-9757.html
It says:
"The provisions of paragraphs (c), (d), (e), and (g) of section 301, and of paragraph (2) of section 308, shall apply as of the date of birth to a person born out of wedlock if-
(1) a blood relationship between the person and the father is established by clear and convincing evidence,
(2) the father had the nationality of the United States at the time of the person's birth,
(3) the father (unless deceased) has agreed in writing to provide financial support for the person until the person reaches the age of 18 years, and
(4) while the person is under the age of 18 years-
(A) the person is legitimated under the law of the person's residence or domicile,
(B) the father acknowledges paternity of the person in writing under oath, or
(C) the paternity of the person is established by adjudication of a competent court."
I think they are requesting evidence that you satisfy item (4) above. Presumably the most standard way to satisfy (4) is through part (C) "the paternity of the person is established by adjudication of a competent court."
I don't think that a power of attorney from your mother is sufficient in this regard. However, there is another way to satisfy item (4), namely through part (B): "the father acknowledges paternity of the person in writing under oath" (however, this had to have happened before you turned 18).
I agree with Jackolantern that you need to speak to an immigration lawyer ASAP.
Are you already 21? If not, there may still be time for your father to file I-130 on your behalf.
