If you need to get a copy of your birth certificate quickly, ask the vital records office at the time you place your order about getting expedited service or shipping.
If You Were Born Abroad, or on a Military Base Abroad
If you were born to American parents abroad, they should have registered your birth with the U.S. Embassy or Consulate in that country, and received a Consular Report of Birth Abroad. You can get a copy of this report from the U.S. Department of State (DOS). Depending on the country, a vital records office in the nation may also list the birth.
If you were born on a military base abroad, and your parents did not register your birth with the U.S. Embassy, you may have to contact the hospital where the birth took place. You may also try contacting the base operator or public affairs office for the appropriate military branch.
If You Were Born Abroad and Adopted by a U.S. Citizen
The country in which you were born issued your birth certificate. If you need a replacement, you must contact the nearest foreign embassy or consulate for that country. A child born in a foreign country and adopted by a U.S. citizen will not receive a U.S. birth certificate. If the document is in a language other than English, you should also seek the embassy’s help in getting the document translated if you require authenticated documents.
If you need to replace naturalization/citizenship documents for a child who was adopted from a foreign country by a U.S. citizen, you will need to fill out an application for replacement of naturalization/citizenship form or contact the U.S. Citizenship and Immigration Service (USCIS) for further help.
