U.S.S.R. DEAR MA. AMBASSADOR: I am writing with reference to the case of Simas Kudirka about whom. I am sure. you have received many inquiries. I understand that Mr. Kudirkas mother has been issued a United States passport and I am writing to inquire whether any determination has been made regarding the possibility that her son. Simas Kudirka. is also a United States citizen. If he does not have a claim to United States citizenship. I would like to know whether Mrs. Kudirka has been advised to execute a visa petition in behalf of her son. With kind regards. Sincerely.
