H1 transfer when date current

Hi,

I have a PD of May 2009, with approved EB2 I 140 from current company. I also have a EB3 I140 from previous company. I am on already well beyond my H1B max out period.

With the current movement of dates, I believe its is possible that may 2009 may be current by end of this year. With new interview requirements, RFE timelines, even if I apply by dec 2019, it might take around a year to get the GC approval. But as luck has it, my current company is not doing great and I might move to a safer workplace before I get GC.

So my question is - while AOS is pending, and if the dates are current, will I be able to transfer my H1 to a different company?

I know I could use EAD to move, but I think its a risky move, incase AOS gets denied I might not have any recourse.

Thanks in Advance!!
