The popular “fast track” US Passport expedited screening program has slowed service because of a a huge backlog of applicants and staff available to process applications. The program, run by U.S Customs and Border Protection, has even had to close some of their airport application centers with staff being moved to help out with other priorities on the southern boarders of the US. The agency says it could take more than 100 days to process a new or renewal application —might be worthwhile to check out other options, especially if just interested in TSA Pre-Check domestic programs???
