U.S. Customs and Border Protection (CBP) issued guidance to non-immigrants who are inadmissible but who do not require visas (principally Canadians) or who have become inadmissible after receiving appropriate documents. The waiver application process is lengthy (taking up to one year) with a cost of $545.00 per application. Non-immigrants must file Form I-192 (87 IR 1699; 8/30/2010).
