好不容易等到了排期，递上了485，又被退回来了。我是主申请人，这次递的是spouse's 485.
It says:
"Your I-485 Application to Register Permanent Residence or Ajust Status is being returned because it must be demonstrated from the priority date of your approved I-140 that there is a visa available for you from your home country. Please provide evidence that your priority date does have visas available for your home country when you re your application. All other adjustment applications must be filed at the local district office."
请问有谁知道这是怎么一回事啊？多谢答复！！！
还有在485表的第二项（part 2) Application type
For spouse, which one to choose?
a. an immigrant petition giving me an immediately available immigrant visa number has been approved.
b. my spouse or parent appled for adjustment of status or was granted lawful permanent residence in an immigrant visa category that allows derivative status for spoused and children.
