American Samoa looks possible if one is a member of the DC bar (California has no reciprocity) and the reciprocity rule is interpreted as trumping the Education rule.
RULE 137. EDUCATION. The applicant must demonstrate the necessary qualifications of learning and ability by proof of having been admitted to practice law before the highest court of record of a State or Territory of the United States or of a foreign country where the English common law forms substantially the basis of that country's jurisprudence, and where English is the language of instruction and practice in the courts of that jurisdiction; provided that such prior Bar admission was premised upon proof of graduation from an accredited law school and successful completion of a bar examination or of equivalent indicia of learning and ability.
Effective August 29, 1989
RULE 138. RECIPROCITY. The fact that an applicant has practiced for a period of 2 years or more before the highest court of record in a State, Territory of the United States, or of a foreign country where the English common law forms substantially the basis of that country's jurisprudence, where English is the language of instruction and practice in the courts of that jurisdiction, and which State, Territory, or country extends reciprocity to American Samoa is prima facie evidence of the applicant's fitness to practice law in American Samoa and to be admitted to the Bar on reciprocity, reserving to the Standing Committee the power to review such circumstances as might be necessary.
