首先谢谢昨天一些网友的答复。
我（主申请人）的485是和140一起递的。485 pending.
现在想递spouse's 485.
6月刚到排期，5/21递的，5/24被退。
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.
网友myturnnow认为：
you already got the returned app, my guess is that your 485 reached CIS mailroom before 6/1. if your pd just became current on june vb, it is supposed to be returned.
我觉得蛮有道理的，但是我还是有点担心。
在485的part 2上，究竟选哪一个。(我选的b）
a. an immigrant petition giving me an immediately available immigrant visa number has been approved.（Attach a copy of the approval notice, or a relative, special immigrant juvenile or special immigrant military visa petition filed with this application that will give you an immediately available visa number, if 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.
我担心移民局会不会认为这是 FAMILY-SPONSORED PREFERENCES（亲属移民），而不是职业移民，要不然，都选那个啊？亲属移民的排期早着呢。
