Not exactly - 回複:回複:Do I have to have a visa during I-485 pendin
For example, an F-1 student does not have to leave the country before finishing his study, even though his I-485 receives a denial, on condition he has used neither AP nor EAD.
In case he has used AP/EAD, then he must leave after the denial of I-485, regardless the expiration of his I-20.
