I 140 status blank in USCIS - Please help in I-140 Posted January 4, 2018 · Report reply Hello Friends, My I 140 was approved in May 2016. I left my employer in April 2017. Recently found that there was some changes (Last Updated column) on my I-140 in USCIS site on Aug 2017. 1) Now my I 140 receipt # is showing up as invalid in the USCIS site, this means its withdrawn / revoked ? Really concerned now. Pls help. 2) If my approved I 140 is withdrawn, can i still switch company from my 2nd employer to another and get H1B extensions ? 3) How can we know if a approved I-140 was revoked / withdrawn ?
