US Soccer International Clearance form
Players who have not lived in the USA prior to the age of 12.

Players 18 years of age and over who are not eligible for the Entry Prior to Age 12 or First Registration options, will need to fill out the ITC Request Form and submit it to U.S. Soccer. U.S. Soccer will then request the ITC from the former federation. Per FIFA regulations, that federation has up to 30 days to respond after which U.S. Soccer can issue a provisional international transfer clearance
