Hello, Please let me know about a web site that I can check immigration fraud on my green cards. I found one website for ss# but is there one for checking immigration cards number for fraud.
Please let me know.
Thank you

If you are confident that somebody is jeopardizing your status, you need to report this matter to USCIS. They share database with other federal government offices such as SSA, DMV, IRS, DOJ, etc. Info will be more accurate than info on website that you don't know who the operator is.
