Form I-140

With speculations that EB-3 may go ahead of EB-2, can we port down to EB-3 from EB-2 using existing labor, in general is it risky to do that, what happens if porting is denied will we loose existing approved EB-2 petition?.

I have my I-140 approved in 2015 and its beyond 180 days now with Employer A.
<br>
If I move to Employer B
a) Consider that Employer A revoked my I-140<br>
b) Please help to confirm will it possible to get multiple extension with previous 180 approved.<br>
c) Even if Employer B doesn't file a Green Card (Labor then I-140)... Can I get multiple extension with Employer A approved I-140

My future employer is planning to file my GC PERM in the month of May 2018. Also I have PERM in process from my current employer.
Is it advisable to join the future employer before filing the PERM or after the PERM is approved or after I-140 is approved.
Basically need to know at what stage of the GC process I can join the future employer.
Does my joining the future employer impact the GC approval process (getting PERM approval, I-140 approval).

I am currently working for a Non-profit org on a cap-exempt H-1B. and my company initiated my GC processing. Below are the few questions:<br>
1. Is the GC processing any different thru a non-profit from a for-profit organization? meaning, is it any advantageous to process my GC thru a non-profit?<br>
2. Can my I-140 from a non-profit be transferred to a for-profit org, if I was able to move to a for-profit org?<br>
3. What are the possible ways that I could move to work for a for -profit organizations? From your previous calls and thru my research I found out below few ways that I could to that. Please give your inputs<br>

a. Finding a profit employer to file my cap-subject H1 (Can I start working for my new employer as soon as my H1b is picked in the lottery or approved, instead of waiting till Oct 1st?)<br>

b. If a new employer sponsor my cap-subject H1 and if I dont move to the new employer, will my current cap-exempt H1 be still active and should I have to go under the cap next time I file a Cap-subject H1<br>

c.applying for concurrent H1b<br>

d. Moving on to H4EAD and filing a H1b next April<br>

e.Joining a Masters CPT college and filing a Cap-subject H-1B next year

I have quick question about the mystery behind 180 days staying with the Employer with whom my I-140 is approved. So my I-140 is been approved with priority date as Dec 2014 and the Notice date is Nov 2017. Do I have to wait for 180 days/ 6 Months from the Notice date of Nov 2017 so I will not loos the Priority date when I move with new employer?

1. While I am moving my H-1 New Employer B, What if something goes wrong during H-1 transfer or after that in GC processing with new employer like RFEs etc comes up, can I move back to employer A if employer A is willing to take me back. Does AC 21 portability rule applied to my case also? Since I have not filed I-485 yet, as per my understanding this rule does not apply to me. While my GC is in process with new Employer B and I am in waiting mode for I-140 approval with new employer, What will happen if my time to extend H-1 petition comes up.
<br>
2. Can I still extend my H-1 with new Employer even if I-140 with new employer is in process and not yet approved. Can I use my old Employers approved I-140 to extend my H-1 in this situation.

My question is about switching from an H-1 to F-1 visa. My six years of H-1 expires in March 2018. I have received an offer for a Phd. at Stanford (starting Aug. 2018) that happens to be one of my dream universities. My employer applied for a PERM back in August 2017, it has not been approved yet. Does the filing of PERM interfere with getting an F-1 visa. I know you’ve answered this question in the past regarding an I-140 and I understand that my chances with just a PERM are slightly better ?

Have an I140 approved with a priority date of Oct 2009 under the EB3 category and worked for the same employer for over 10 years from 2007 - 2017
I filed for my AOS in December 2017 using Cross Changeability since my spouse is born in Malaysia
I left my employer after 2 weeks of filing the AOS for a better opportunity in terms of Compensation
I used my approved I140 to get three years of H1b extension. My new job and position are in the same category and my new employer is ready to provide Supplement J if needed
It has been almost two months since the filing and have received all the receipt notices and have also done the fingerprinting and haven't received any RFE Yet. Do you foresee any issues arising in near future and jeopardizing the application because I left my employer before 180 days of AOS pendency?
