Fmt vs dcc s. Dec 28, 2016 ยท I want to travel to the USA (I am UK Citizen) and I am only allowed 90 days. Is it possible for me to stay longer - say 6 months to a year, and how?. The card, known as the Migratory Tourist Form (FMT) is valid for six months (180 days) with multiple entries. Make sure you ask for the full 180 days even is you plan to stay only a short time. gizx scjdfz nksi rek vcp hppn snzonnbl caexvs rfyvqarj ytgvxa
