1. 我们的不是PERM，是2001年4月份申请的Labor Certificate。
-Lab Certificate is the same thing as PERM. Was your I-140 approved yet? If it is approved, your employer may file another PERM/I-140 and use this old priority date. Talk to your lawyer, anyway.
2. 移民局现在Challenge的是公司2001年的Tax Return不足以支付我的薪水。
-I think USCIS is too picky.
3. 根据您以上的说法，可否有据可查？

Note this in the article:
" Ability to pay is measured at the time the job is initially offered, that is when the labor certification is filed, and ability to pay must continue throughout the course of the case until the I-485 is approved".
