I have no such experience and these are not your exact facts, but:
Rev. Rul. 61-118
Where Cuban refugees enter the United States under a temporary visitors visa, within a few months request political asylum, and are granted indefinite departure status with the right to work in this country, or are admitted to this country as parolees under section 212(d)(5) of the Immigration and Nationality Act, 8 U.S.C. 1182(d)(5), they are classified as alien residents of the United States rather than nonresident aliens for Federal income tax purposes. See Rev. Rul. 57-331, C.B. 1957-2, 11, which relates to Hungarian refugees.
Rev. Rul. 57-331
Where a Hungarian refugee enters the United States under an immigrant visa for permanent residence in this country, or is admitted to this country as a parolee under section 212(d)(5) of the Immigration and Nationality Act, 66 Stat. 188, 8 U.S.C. 1182(d)(5), such refugee is classified as an alien resident of the United States and is subject to Federal income tax under the provisions of section 1 of the Internal Revenue Code of 1954, in the same manner as is a citizen of the United States. Therefore, amounts paid to such a refugee for services performed within the United States, which constitute wages for purposes of the Collection of Income Tax at Source on Wages (chapter 24, subtitle C, Internal Revenue Code of 1954), are subject to income tax withholding under section 3402 of the Code.
Since the Federal Insurance Contributions Act taxes are applicable to all "wages" for "employment," as those terms are defined in the Act (chapter 21, subtitle C, Internal Revenue Code of 1954), wages paid to such a refugee for services in an employment under the act are subject to such taxes. The fact that an employee is a Hungarian refugee is immaterial in determining whether services performed within the United States by such an employee constitute "employment" for purposes of deducting, under section 3102 of the Act, the employee tax imposed by such Act.
