text: It depends upon the agency.  Under the 'frequently asked questions' of the CIA for example, a marriage or relationship with a foreign national may affect security processing or eligibility to receive a security clearance.\n\n"The agency is required to consider its applicant's relationship with foreign nationals.  The particular concern is if any member of an applicant's family is a citizen of a foreign country.  At the Agency, if the applicant's spouse, intended spouse, or live-in relationship is not a citizen of the US, the Agency will perform security screening of this individual as part of the applicant's security processing.  The foreign national will be asked to sign an authorization for release of information, provide biographic data for a a background investigation, and undergo a polygraph examination.  Furthermore, a condition of employment for Agency employees is that their foreign national spouses et al, must agree to become a naturalized US citizen as soon as eligible under standard immigration procedures.  The Agency will render a decision to hire an applicant only after both the applicant and the foreign national favorably complete security processing."
