Topic: I-140 approved and in India, need to know the options.

Hello Friends/experts, Need advice I 140 approved and in India, need to know the options. I used to work in USA till April 2017. Till that time my 6 years got completed on h1b visa. Then I came back to India. My employer in USA worked on my perm and other stuff and it got approved in December 2017. They have my approved I 140 and I have a copy of that. I want to know what can be done if I want to go back to USA? My employer told me that due to current administrations they don’t want to take the risk and they are not looking for any opportunity for me so they have not yet applied for my H1b extension as without job letter/client letter it cannot be done It will be really helpful if someone can guide me, what options are available for me if I want to come back to USA? Thanks, Pushpak.
