发帖数: 73 | 1 几年前用OPT EAD时候，上面有一个 Alien number.
两年前拿到140的 Approval －－－－ 140 form上的第 11项，就是Alien number.
140 form上，律师填的Alien number就是我 OPT EAD上的A number, 但从140 Approval
Notice上看，USCIS划掉这个数字，改成另外一个数字。
不知道这种差异会不会导致将来的问题。 |

发帖数: 25 | 4 Dear friends,
I set up an apache server 1.3.9 and bind the port 8080. But
recently I downloaded a counter which automatically tries
to bind to port number 3000, and unable to bind to it. Don't know
what I should do. Should I change the apache server to 3000?
I tried it but it refused to accept the change (the httpd won't
start if I change the port number). Or is there anyway I can
free up my port number 3000? I remember when I tried an iplanet
web server before, I assigned a port number to be 30 |

时候才会获得对应申请类别的visa number？对于这个问题，有关法律的回答是：
首先，申请人必须在相应的visa category 开放(current) 的情 况下才可以提出I-485
申 请。在提交申请后，USCIS会对此申请进行审核，然后可能会批准此申请并给予一个
visa number。在移 民官批准此申请时，visa bulletin相应类别也应该是开放的才可
以给予visa number。如果当时的visa bulletin不 是开 放的，那么USCIS 就会等到新
的visa number 发放之后才会批准申请。简单来说，申请在提出时及批准时，visa
bulletin都应 该是开 放的。
以上是法律规定的程序，但是也有不少人指出事实上一 些I-485申 请案 件即 使在
visa bulletin不开放的情况下也有被批准。导致这种情况的出现往往是因为visa
bulletin 在 current 和 not current状态之间突然改变的时候。有时候移民官在visa
