FOIA and Privacy Act

1. I have my I-140 approved 2 months back and my employer is not ready to share the approval notice, is there any way to get it?

2. I am planning to look out for a job change and will my I-140 still be there if I change my employer or is there any time period I have to be with the employer or can they revoke my I-140??, as I am planning to get EAD for my wife on my I-140.

I'm an Indian, living in Canada on PR. I recently applied for a visit visa to the US, and got denied. The main questions I got were regarding University of Farmington. It was a fake university setup by ICE, and then they did a swoop and arrested and deported a lot of the students. I was enrolled into Farmington from Feb 2017 - Feb 2018. <br>
I was asked if:<br>
1) How I didn't think it was weird that there were no classes?<br>
My response - Well yes, that's why I left after a year<br>
2) So what did you do for a year?<br>
My response - waited on more information from the university regarding class timings, and just kinda hung around<br>
3) I was pressed on what I did when I was hanging around, how I paid for things<br>
My response - I worked during that time<br>
<br>
The officer typed up something into the screen for sometime (I'm assuming it's whatever was discussed above) and gave me a denial.
<br>
I did not want to start a debate about immigration laws or how this was Entrapment, or the "bait car" tactic. I thanked him, took my passport and the pink rejection letter and left.<br>
What are my options ahead? Should I:<br>
1) Re-apply and give it another shot?<br>
2) Wait to become a Canadian citizen, then apply?<br>
3) Enroll into an organization that has conferences and such in the US, and based on an upcoming conference (eg: Chicago, or NY), then apply for that conference only?<br>
4) Hire a lawyer to fight this in court as being unfair.

1. My employer filed my I-140 and it was approved. They refused to provide me the approval notice but through InfoPass I was able to get my receipt number and Alien #. To port my priority date, I would like to request USCIS for the duplicate copy of I-140 approval notice.
2. Is it possible to request USCIS a duplicate copy of my I-140 approval notice using either G-639 (FOIA) or I-824 (Action on an approved application or petition) or any other method as I have my receipt#?
