Change of employer after I-140 approval

[scorpian69]

Hi,

Currently I am on H1B visa, completed 6+ years. My I-140 got approved in 2015 having priority date of June 2015. I have been with the same employer since then. My recent H1B extension got approved last month, got extension till June 2019.

Now, I am planning to change the employer. What all things my new employer needs to take care of before my current H1B expires (i.e. June 2019) so that my H1B status doesn't jeopardize.

Thanks
