If you feel that you have a claim to U.S. citizenship, you must appear in person at a Consulate/Embassy and submit the following items:

United States Citizenship for Adults Born Abroad

Persons born abroad to U.S. parent/s may have acquired U.S. citizenship at birth. This determination is based upon a variety of factors: the law in effect at the time of birth, the amount of time the American citizen parent/s have lived in the U.S. prior to the birth, and, in some cases, the marital status of the biological parents.

The following information summarizes key provisions of U.S. law regarding the transmission of citizenship by a U.S. citizen parent or parents to their child born in wedlock outside the USA (please note that separate transmission requirements apply for children born outside of wedlock):

The acquisition of U.S. citizenship by birth outside the United States is governed by Federal statutes and is based on jus sanguinis, the right of blood. These laws on acquisition of U.S. citizenship through a parent have always been based upon the existence of a blood relationship between the child and parent(s) through whom citizenship is claimed.

  • If both your parents were U.S. citizens when you were born, you may have acquired U.S. citizenship at birth, if one parent resided in the USA prior to your birth (applies to persons born anytime after 12 Noon Eastern Time, 5/24/34).
  • If you were born on or after 11/14/86, and one of your parents was a U.S. citizen at the time of your birth, you may have acquired U.S. citizenship at birth if the U.S. citizen parent was physically present in the USA for periods totaling 5 years prior to your birth, at least 2 of which were after their 14th birthday.
  • If you were born on or after 12/24/52 and before 11/14/86, and one of your parents was a U.S. citizen at the time of your birth, you may have acquired U.S. citizenship at birth if the U.S. citizen parent was physically present in the USA for periods totaling 10 years prior to your birth, at least 5 of which were after their 14th birthday.
  • If you were born on or after 1/13/41 and before 12/24/52, and one of your parents was a U.S. citizen at the time of your birth, you may have acquired U.S. citizenship at birth if the U.S. citizen parent resided in the USA for periods totaling 10 years prior to your birth, at least 5 of which were after their 16th birthday (slightly more expansive provision for children of U.S. military veterans).
  • If you were born after 12 Noon Eastern Time 5/24/34 and before 1/13/41, and one of your parents was a U.S. citizen at the time of your birth, you may have acquired U.S. citizenship at birth if the U.S. citizen parent resided in the USA prior to your birth.
  • If you were born before 12 Noon Eastern Time 5/24/34, and one of your parents was a U.S. citizen at the time of your birth, you may have acquired U.S. citizenship at birth if the U.S. citizen parent resided in the USA prior to your birth.
  • Important Note: If you qualified for citizenship in one of these categories, note you may have lost it for failure to live in the USA for a certain period. Your citizenship may, however, be restored upon your taking an oath of allegiance to the U.S.
Checklist
  1. Citizenship Questionnaire - See below.
  2. Complete Form DS-11. Do not sign.
  3. Applicant's official Provincial Birth Record, showing complete information on the parents.

    Note: Some posts can only accept an original Registration of Live Birth - bearing the impression seal of the Vital Statistics office. This record is kept on file with Vital Statistics and a certified photocopy bearing the impression seal of the office can be issued.

    This document tells us whether there have been any amendments to the record. The child's certificate of birth is not always acceptable. Please refer to your "post specific" instructions when you receive your application forms, for acceptable birth record instructions.

  4. Applicant's Identification such as a driver's license, student I.D. or Canadian passport.
  5. Evidence of Applicant's Name Change (if applicable): Present your marriage certificates, divorce decrees, adoption papers, or court-ordered name changes. This is important for women whose last name has changed since birth because of marriage(s).
  6. Evidence of Parent(s) U.S. Citizenship: U.S. passport, Certificate of Citizenship/Naturalization, Consular Report of Birth Abroad, or a U.S. birth certificate bearing the impression seal of the vital records office that issued it and including the date of filing. If you do not have a certified copy of your parents' birth record, write to the vital records office in the state, county, or municipality where your U.S. citizen parent or parents were born. Many records from the turn of the century are not readily available. If none of the vital records offices listed above have a record, keep the replies and try to obtain secondary evidence, such as a census record or a baptismal record showing date and place of birth. All correspondence from these places must be submitted with your application.

    Note: If you were born before May 24, 1934, you will have acquired your U.S. citizenship through either your mother or your father. You need only submit evidence of U.S. citizenship for one or the other, not both. If you were born after May 24, 1934, to two U.S. parents, submit evidence of U.S. citizenship for both of them.

  7. Certified copy of the Parents' Marriage Certificate.
  8. Documentary evidence of termination of any previous marriages of either parent (i.e. divorce decree, death certificate, etc.), if applicable.
  9. Evidence of your parents residence/physical presence in the U.S.:
    • If you were born between Jan. 13, 1941 and prior to Dec. 24, 1952, to one U.S. citizen parent, you will need to present evidence of the periods during which your U.S. citizen parent resided in the U.S.
    • If you were born on or after Dec. 24, 1952, to one U.S. citizen parent, you will need to present evidence of the periods during which your U.S. citizen parent was physically present in the U.S.
    • If you have two foreign-born U.S. citizen parents, you must present evidence that at least one of them resided in the U.S. prior to your birth.

    Note: Physical presence is not the same as residence. For example, if a person was residing in the U.S., but left for vacations or schooling abroad, the person was not physically present in the U.S. during those periods of time.

    1. Submit your parent's Canadian Immigration Record showing original entry to Canada from the U.S. Other evidence may be required by the Consul, such as school records, military records, employment records, etc.
    2. If you were born after Jan. 13, 1941 and your U.S. citizen parent is still living, have that parent complete the Affidavit of Parentage and sign it before either a U.S. Consular Officer or a Notary Public.
    3. If your parent is deceased, submit the death certificate and other evidence, as above.
  10. Photographs: Submit two recent, identical color passport photographs, two inches by two inches, as described on the back of form Form DS-11 Passport Application.
