It's the Adjudicator's Field Manual. Go to Chapter 53 Refugee Travel Documents, Section 53.3 Adjudication
These are some interesting excerpts from the document:
"Normally, once an alien becomes a refugee or asylee, he or she retains that status UNTIL he or she becomes a permanent resident."
"(2) Alien Has A Travel Document From His/Her Country . Similarly, if the applicant is in possession of a valid travel document from the country of nationality, the Form I-131 may also be deniable. There is no absolute prohibition against issuing a travel document to permit a refugee to travel to the country of last residence or nationality; however, travel to that country may preclude the alien from establishing eligibility for permanent residence under section 209 of the Act.
In the absence of proof to the contrary, a refugee who applies for and obtains a national passport or its renewal will be presumed to have intended to re-avail or return to the protection of the country of persecution. However, obtaining other documents, such as birth or marriage records, cannot be regarded as re-availment of protection. Some countries may issue passports without intending any protection to the recipient.
(3) Alien Intends to Visit Home Country . There is no prohibition against issuing a travel document to permit a refugee to travel to the country of last residence or nationality; however, travel to that country may raise doubts about whether the alien has re-availed (or intends to re-avail) him or herself of the protection of the country of persecution. It may also preclude the alien from establishing eligibility for permanent residence under section 209. Each case must be judged on its own merits. For example, visiting an old or sick parent should be considered a more worthy reason for visiting one's home country than regular visits on holidays or business trips. The applicant should therefore be referred to the local USCIS office for interview and the possible taking of a sworn statement.
