What is the allowable time interval between the overseas examination (validity period) and U.S. arrival?
The allowable time interval between the completion of the overseas examination and U.S. arrival is 12 months. If the applicant has a Class A or TB classification, the interval is 6 months. For Hmong and Burmese refugees resettling from Thailand, the allowable time interval between the overseas examination and U.S. arrival is 3 months, regardless of whether the refugee has a TB classification. For Class B1 refugees, the 3-month interval begins when the culture results are reported; culture results are usually reported within 8 weeks of sputum collection.
