It is rare that a 副申请人 get GC before the 主申请人. It is possible (very likely) that your background check is not clear yet, that's why you want to find out your detail status. Another possibility is your file has been separated from 副申请人, see below. http://www.dhs.gov/xfoia/gc_1306427283101.shtm#2 Pending Derivative Form I-485s Due to File Separation Updated 11/6/2009 Do you know of a situation where USCIS approved the Form I-485 (Application to Register Permanent Residence or Adjust Status) for a principal applicant, but the derivative family members' (spouse or minor children) Form I-485 applications remain pending? While in some cases this may be due to missing evidence, security clearance difficulties, or some other legitimate reason, the file may just be separated from the principal's. If a family member's derivative adjustment of status application has been pending in excess of 30 days from the approval date of the principal applicant's Form I-485, please submit to c************************[email protected]: * DHS Form 7001 * A copy of the principal applicant's Form I-485 approval notice, * A copy of the Form I-485 receipt notice for the derivative, * A copy of the approved immigrant visa petition notice (if employment- based), and * Any other evidence that is pertinent to the case. In your email, please note in the subject line: "Unapproved Derivative I-485 ." We will look into your case and review how we may be of assistance.
