已經綠卡了，要海歸2-3年。準備申請回美紙。還有一個月的時間就要回去了。
聽說申請回美紙的時候必須人在美國，
可否申請後回中國，然後收到打指紋通知再回美國打指紋。然後再回中國等待批準。
-Yes of course.
如果在美國隻有一個月時間，是否可以加急申請？如果可以，現在加急，加上打指紋，共需多久？
-If you have emergency such as family reasons (e.g. illness, etc.), business reasons (e.g. business meeting, etc.), you can request expedited processing for fingerprinting which may take about three weeks.
For requiring expedited processing, you should submit an email address and fax number (if any)along with two pre-paid, self-addressed express mailers along with the Form I-131. If USCIS approves the expedite request, the pre-paid express mailers will be used to return the ASC appointment notice and the reentry permit once the application has been adjudicated.
