國內工作原因需要盡快回國，能否收到回美證申請Receipt Notice後馬上去指模？
-No. You need to have the biometrics appointment notice in hand first. When you file I-131 fro reentry permit, you may request expedite biometrics, thus you may get the biometrics appointment notice in about 10 to 14 days. See the following at:

Q. What are the procedures for requesting an expedited adjudication of Form I-131?
A. If applicants require expedited processing, the instructions provide specific information for submitting pre-paid express mailers with the Form I-131 for USCIS to send the applicant his or her receipt and ASC appointment notice, as well as the completed re-entry permit or refugee travel document, if approved. A request for expedited processing should contain the applicant’s reasons for such processing so that USCIS may determine whether the applicant qualifies for expedited processing.
