Send the official letter, request, or RFE. It usually identifies the case or file number, people to be tested, relationship to verify, and any deadline. The agency’s instructions determine where overseas samples are collected and how results must be delivered.
For an embassy or consular case, the laboratory coordinates kit shipment and sends the report through the required agency channel. Participants should not handle agency-directed test kits.
