很多J-1持有人都需要遵守有关Two-year home residency requirement的规定，即在J-
1身份结束后，申请人必须在原国家(country of last permanent residence) 居住满2
年才可以再以其它身份回美。以下为有关信息：
Many J-1 visa holders are subject to what is known as the two-year home
country physical presence requirement of Section ?12(e) of the Immigration
and Naturalization Act. This means that upon completion of a J visa term,
the J beneficiary must live in either their home country or their country of
last permanent residence for at least two years before return
