除了在绿卡颁发的时候易经结婚2年以上的情形以外,婚姻绿卡一般都是条件绿卡(
conditional residence status)。两年时间的计算从婚姻绿卡颁发当天开始。
夫妻双方必须在绿卡颁发第二年的90天之内递交I-751。(Must file joint petition
Form I-751 within 90 days of second anniversary of grant of conditional
residence. )
条件绿卡颁发两年之后就变成永久绿卡。(Conditional residence becomes
permanent after second anniversary of status if it is not terminated.)
夫妻双方如果一方病逝,无法同时递交申请I-751,可以申请waiver.
家暴被施虐的申请人配偶可以自己递交I-751申请,并申请waiver。
(另外,家暴被施虐的公民或绿卡配偶可以申请VAWA Self-Petitions for Permanent
Residence.)
