今天有读者问：「 我们的 F3 排期已到，我和妻子在国内，小孩（已过18岁）已去美念书，这种情况小孩是单独在美转换身份，我和妻子去广州面签好呢？还是一家共同去广州面签好呢？」这是个有意思的问题。
根据 USCIS 的 I-485 说明[来源]，附属申请人在以下情形可以提交申请调整身份（AoS）：
1. At the same time the principal applicant files Form I-485;
2. After the principal applicant filed a Form I-485 that remains pending a final decision by USCIS;
3. After USCIS approves the principal applicant’s Form I-485, if the principal applicant is still a lawful permanent resident and if, at the time of the principal applicant’s Form I-485 approval, you were the principal applicant’s spouse or child; or
4. After the principal applicant obtained an immigrant visa and entered the United States as a lawful permanent resident if the principal applicant is still a lawful permanent resident and, at the time of the principal applicant’s entry, you were the principal applicant’s spouse or child.
- 与主申请人同时提交 I-485。
- 主申请人已提交 I-485 但尚未批准，附属申请人可以申请 AoS。
- 主申请人 I-485 获批且绿卡未放弃或撤销，符合资格的附属申请人可以 AoS。
- 主申请人在境外获得移民签证、进入美国成为永久居民后，符合资格的附属申请人可以 AoS。
上述读者的情形符合最后一类。他和妻子在中国通过面试、拿到签证、进入美国之后，他的孩子即可在美国申请调整身份。领馆处理程序，从有签证名额开始，到最终面谈通过拿到签证，可能会长达8-12个月。至于哪种方案更有利，建议此类情形的读者请移民律师详细咨询。
