In order to show that my GC is in progress, what do I have to carry with me. My GC is still at the Labor stage and I have a copy of a document called the "Confirmation of Pending Labor Certification Application". This document is on the "Employment Development Department, State of California" letterhead. This document has the date that my labor was filled and the case number. Will this copy be enough?
---- The letter accepted for the proof of GC (meaning has someone applied for an immigration petition applied on your behalf) is an approved I -140.
------------------ LC is the first step for Employment based GC , I-140 is filed after LC approval.
(one can also file I-140 with out employer if one is eligible foe EB1)
All other correspondence is only in the initial stages and shows your intention and to show your capabilities for a job you intend doing for your company.
For an 8th year extension, many times the VO may ask for proof/evidence of having applied for an immigration petition meaning I-140.
---------- where did you read that? one can get H1 extension based on LC pending more than 365 days and if I-140 approved on can get H1 extension for 3 years
