Did you (semigage) copy your post from some website and posted here. It looks so and more complicated.
Hnks, I have applied for I-485 based on approved I-40 EB1-EA. You can send the similar documents that I sent to USCIS. You need not sent employment letter
These are the documents I sent and my case has been approved.
List of Documents to apply for I-485
1. Form G-28, if represented by a lawyer
2. Form -1-485 and filing fee ($1010.00)
3. Forms I-765/I-131 (Optional only and note that there is no separte fee for this under new fee system)
4. Form G-325 (all four copies)
5. Copy of I-140 approval notice
6. If were in J-1, send appoved I-612 form
7. Current Immigration status showing your current status in US (even if its expired, like DS-2019 for J-1 or I-129 for HIB).
8. Record of current employment and wage report- for this send earnings statement for last 4 months, and last year's W-2 and federal Tax return (Joint tax returns if married).
9. Medical report in sealed envelope given to you by your doctor. (Make sure you do your PPD skin test for TB. If its -ve, dont take X-ray or take X-ray if its +ve. If you only take X-ray without PPD, it will invite for an RFE. See SOP for I-485.
10. Passport data page showing your name, DOB..and page that shows your last US visa (Dont SEND all pages of your passport).
11. Photocopy of both pages of your last I-94.
12. Two photos for I-485 or Six if filing I-765 and I-131 together. See Dept of State/USCIS regulations for passport size photos-2x2.
13. Birth certificate. If your BC is not in english, then attach a translation certificate in english and with a notary signing that translator knows both English and the language in which BC was written. If you dont have BC, then Non-availability certificate from respective authority in your country (look at
http://travel.state.gov/visa/frvi/reciprocity/reciprocity_3272.html to see authority who gives BC in your Country, USCIS follows this book only for BCs, check I-485 SOP) and two affidavits from your parents and relatives.
14. Marriage certificate
For Spouse, If you are applying I-485 for spouse, then similar as listed above and any document to show that your marriage is legitimate, like joint tax returns, insurances, family plan phone, mortgage, and rental agreement. This is just to avoid an RFE from USCIS.
Note: You do not need to SEND employment letter because you have already shown your intent to work in in your field in US when you filed your I-140. I have listed purely based on my I-485 experience and an RFE I received for my spouse.
I was in J-1 in 2005 and never filed tax return for 2005 becasue of tax treaty and Filed tax returns for 2006 and 2007 (joint tax return since I got married in 2007) only. During 2006, I worked in US for only 3.5 months and submitted W-2 and Tax return for 2005 only and without any problem I got apporved. In fact We filed tax return for 2007 after mine one got approved and my spouse got RFE to show additional documents for marriage proof.
Dont get confused by anyone and read I-485 filing incstuructions carefully. For employer filed GC only, USCIS requests all tax returns, employment letter....etc.. Both EB1-EA/NIW are self petitioned one and send only earnigs statement to show that you are working and wont be a public burden to US.
Hope this clears your doubt and good luck with your AOS.
