Hello,

I'm on H1B visa. My company started the green card process, obtained labor certificate, then filed I-140 (EB3 Category) and still waiting.
Can I switch to another company without interrupting the Green Card process? I need to take advantage of what has been obtained so far if the new company is willing to continue the process.
Would it make difference if I leave my company before or after filing I-485?

Thanks
