Chapter 4 - Spouses of U.S. Citizens Employed Abroad
The spouse of a U.S. citizen who is “regularly stationed abroad” in qualifying employment may be eligible for naturalization on the basis of their marriage.  Spouses otherwise eligible under this provision are exempt from the continuous residence and physical presence requirements for naturalization. 
The spouse must establish that he or she meets the following criteria in order to qualify:
Age 18 or older at the time of filing.
LPR at the time of filing the naturalization application.
Continue to be the spouse of the U.S. citizen up until the time the applicant takes the Oath of Allegiance.
Married to a U.S. citizen spouse regularly stationed abroad in qualifying employment for at least one year.
Has a good faith intent to reside abroad with the U.S. citizen spouse upon naturalization and to reside in the United States immediately upon the citizen spouse’s termination of employment abroad.
Establish that he or she will depart to join the citizen spouse within 30 to 45 days after the date of naturalization. 
Understanding of basic English, including the ability to read, write, and speak.
Knowledge of basic U.S. history and government.
Demonstrate good moral character for at least three years prior to filing the application until the time of naturalization. 
Attachment to the principles of the U.S. Constitution and well-disposed to the good order and happiness of the U.S. during all relevant periods under the law.
The period for showing good moral character (GMC) for spouses employed abroad is not specifically stated in the corresponding statute and regulation.  USCIS follows the statutory three-year GMC period preceding filing (until naturalization) specified for spouses of U.S. citizens residing in the United States. 
In general, the spouse is required to be present in the United States after admission as an LPR for his or her naturalization examination and for taking the Oath of Allegiance for naturalization. 
A spouse of a member of the U.S. military applying under this provision may also qualify for naturalization under INA 316(a) or INA 319(a), which could permit him or her to be eligible for overseas processing of the naturalization application, to include interviews, filings, oaths, ceremonies, or other proceedings relating to naturalization. 
The spouse of a U.S. citizen employed abroad is not required to have lived in marital union with his or her citizen spouse.  The spouse only needs to show that he or she is in a legally valid marriage with a U.S. citizen from the date of filing the application until the time of the Oath of Allegiance.  Such spouses who are not living in marital union still have to show intent to reside abroad with the U.S. citizen spouse abroad and take up residence in the United States upon termination of the qualifying employment abroad. 
Qualifying employment abroad means to be under employment contract or orders and to assume the duties of employment in any of following entities or positions: 
Government of the United States (including the U.S. armed forces);
American institution of research recognized as such by the Attorney General; 
American firm or corporation engaged in whole or in part in the development of foreign trade and commerce of the United States, or a subsidiary thereof;
Public international organization in which the United States participates by treaty or statute; 
Authorized to perform the ministerial or priestly functions of a religious denomination having a bona fide organization within the United States; or
Engaged solely as a missionary by a religious denomination or by an interdenominational mission organization having a bona fide organization within the United States.
A person applying for naturalization based on marriage to a U.S. citizen employed abroad must establish that his or her citizen spouse is regularly stationed abroad. A citizen spouse is regularly stationed abroad if he or she engages in qualifying employment abroad for at least one year.  Both the statute and its corresponding regulation are silent on when to begin calculating the specified period regularly stationed abroad. 
As a matter of policy, USCIS calculates the period of qualifying employment abroad from the time the applicant spouse properly files for naturalization.  However, this policy does not alter the requirement that the applicant must intend to reside abroad with the U.S. citizen spouse after naturalization. 
Accordingly, the spouse of the U.S. citizen employed abroad may naturalize if his or her U.S. citizen’s qualifying employment abroad is scheduled to last for at least one year at the time of filing, even if less than one year of such employment remains at the time of the naturalization interview or Oath of Allegiance provided that the spouse remains employed abroad at the time of naturalization.
The burden is on the applicant to establish that his or her U.S. citizen’s qualifying employment abroad is scheduled to last for at least one year from the time of filing.
Spouses of U.S. citizens who are regularly stationed abroad under qualifying employment may be eligible to file for naturalization immediately after obtaining LPR status in the United States. Such spouses are not required to have any prior period of residence or specified period of physical presence within the United States in order to qualify for naturalization. 
A spouse of a U.S. citizen who is regularly stationed abroad under qualifying employment is required to be in the United States pursuant to an admission as an LPR for the naturalization examination and the Oath of Allegiance for naturalization. 
Application for Naturalization (Form N-400)
To apply for naturalization, the spouse of a U.S. citizen employed abroad must submit an Application for Naturalization (Form N-400) in accordance with the form instructions and with the required fee.  The applicant should check the “other” eligibility option on the naturalization application and indicate that he or she is applying pursuant to INA 319(b) on the basis of marriage to a U.S. citizen who is or will be regularly stationed abroad.
Evidence of Spouse’s United States Citizenship
Under this provision, the burden is on the applicant to establish that he or she is married to a U.S. citizen.  A spouse of a U.S. citizen must submit with the application evidence to establish the U.S. citizenship of his or her spouse. 
Evidence of U.S. citizenship may include:
Certificate of birth in the United States;
Department of State Consular Report of Birth Abroad (FS-240);
Certificate of Citizenship;
Certificate of Naturalization; and
Valid and unexpired United States Passport.
If an official civil record cannot be produced, secondary evidence may be accepted on a case-by-case basis. An officer has the right to request an original record if there is doubt as to the authenticity of the record. 
Evidence of Citizen Spouse’s Employment Abroad
Along with his or her naturalization application, the applicant must submit evidence demonstrating the spouse’s qualifying employment abroad. 
Such evidence may include:
The name of the employer and either the nature of the employer’s business or the ministerial, religious, or missionary activity in which the employer is engaged;
Whether the employing entity is owned in whole or in part by United States interests;
Whether the employing entity is engaged in whole or in part in the development of the foreign trade and commerce of the United States;
The nature of the activity in which the citizen spouse is engaged; and
The anticipated period of employment abroad.
Evidence of Applicant’s Intent to Reside Abroad with Citizen Spouse and Return to the United States Upon Termination of Qualifying Employment
Along with his or her naturalization application, an applicant for naturalization under INA 319(b) must submit a statement describing his or her intent to reside abroad with the citizen spouse and his or her intent to take up residence within the United States immediately upon the termination of such employment abroad of the citizen spouse.
