H1b Extension with new employer after 6 year limit

[KK485]

Hello,

I have the approved I-140 from my previous employer since 2016 with priority date 2015 March. I changed my employer in 2018. Now My end client offered me a permanent position without commitment for Green Card Sponsorship. I started using H1B from 2014. If  I change my employer without having green card sponsorship and anytime my priority date(March 2015) becomes current, Will I be out of status?

Also, Will I not be eligible to extend my H1B beyond 6 year limit?

Thanks in Advance.

my priority date(March 2015) becomes current, -- this is distant future do not depend on this.

Also, Will I not be eligible to extend my H1B beyond 6 year limit? - I guess without GC process 6 years is limit.
