If new legislation proposed by Cotton and Purdue passes to remove the IR5 category (parents of USC), what happens to change of status (I-130/I-485) petitions in progress?

1) Is it true H-4 EAD rule will be revoked by the government? <br>
2) My H-1B visa is going to expire in 14-Jan-2018 and if my employer submits my PERM application in the month of June (i.e. before 6 months of my current 6 years of H-1B visa duration).<br>
a) If my PERM is not approved before my current H-1B visa expires. Can I change to H-4 EAD at that time?<br>
b) If my PERM approved after change to H-4 EAD, Can I change back to H-1B?<br>
c) Is it possible to convert from H-1 to H-4 EAD without taking a break in employment?<br>
d) If my PERM gets approved after my current H-1B expires can my employer file for H-1B extension?<br>
3) I would like to move to H-4 EAD but I would like to come back to H-1B anytime in future, in that situation what is the best status for H-1B?<br>
4) If I apply for new H-1B is it comes under H-1 quota (After 6 years completes.)?

I am a physician currently in H-1B undergoing 3 years of J-1 waiver program which is set to be completed on July end of this year. My husband got his greencard through E-B2 category (rest of the world) in early 2013 When I was still in J-1. My name was included in I-140 but could not file I-485 due to my J-1 visa. I have been married since 2006 and came to the US initially on H-4 visa before getting residency in J-1 visa. Is there a possibility of filing my I-485 directly without waiting for the long I-130 approval process? Or is there any exceptions for a situation like mine such that spouse happened to be in J1 and could not apply for a change of status at the time primary applicant applied for I-485?

My I-140 (EB2) approved. Priority Date: 1st July 2009. Wife on H4 EAD. H1B expires in October 2018. H1B and EB2(GC) were filed for "software engineer" position. I got an offer from a different employer, they are offering me "Director of Dev. services". Q1. According to Feb bulletin, final EB2 application date is 15 April 2008. Knowing that dates are so close, I am not sure whether to switch to the new employer and start GC fresh OR stick to the existing employer as dates are close.Q2. If I move to a new employer and take "Director" position, Will this impact my H1B and Green Card, as the roles and responsibilities are different between "Software Engineer" and "Director of Dev. Services"? Does the new employer needs to start fresh GC process for "Director" position?

I have an approved I-140 with priority date 2013 from employer A and my employer A is withdrawing it. I am going to apply I-140 with employer B now in regular processing and also porting the date. I will complete my 6 years of H-1 end of the year. Will I still be eligible for 3 years of H-1 extension with my approved I-140 from employer A?
