thank you. Things escalated over the holiday. I recorded him talking sexually and declaring love for another woman he knew before marrying me and they were talking about me viciously and laughing about using me. My parents asked him to return the house keys and leave and he refused and challenged them to call the cops we they had no choice. They made him return the key and waited until he left.   I have had to return with my children to the state where I work but he is hanging around working near where my parents live. My brother hired him and we are pretty much hostages

A good heart is a good thing.
Conversely, don't be so open-minded that your brains fall out.

Hi,
 
Sorry you are in pain.

Divorce and move on.  Get a restraining order if you feel unsafe.  Your safety should be your first priority.  
 
There's nothing you can do about his green card.  If you divorce, he can file to remove the condition on his own.  If you don't divorce, he would need your participation to remove the condition.  This would force him to file for divorce in order to remove the condition on his green card.  

Best of luck.  

If he feels that way I can understand. I would send a letter to immigration stating fraud and what evidence I had. It may not change a thing as far as he is concerned but it may go in her file and it could help establish a pattern of behavior to help someone in the future or keep her from other fraud like bringing a new 'already selected' spouse into the country. It may make him feel a little closure knowing he did all he could do, too. However, after doing that, being heard which he deserves if he needs it, then he needs to move on, not check back or keep tabs. Let them handle it. If they want to talk with him them the will but let it go. All this in my opinion only of course. 
Hey, most of us have been used at least once in our lives so you are in good company and there are a lot of people here who genuinely wish you good things and are doing their best to give you good advice. That's something. Sorry, it happened to you!

for what it's worth, i would suggest making the report anyway. from the details you've shared here OP, she seems to be pretty knowledgeable about the immigration process and knows how to work it in her favor, and so who knows if she might do something somehow in the future to get you court to enforce the I-864 you filed for her. reporting her would, (at least i think so) get your side of the story documented in her file now. i feel like the sooner that report gets added on her the more credence it will have over time, just in case everything gets thrown into question. now, with this said, don't expect anything to come out of the report (as in, ICE or CBP investigating or doing any action at all) because i agree with what others have said on here in that they most likely will not do anything like that. report and take that as your closure.

The OP is free to report it, of course.......but I doubt it would have any result.  After all, he gave USCIS and DOS ample  evidence that the marriage was bona fide.......marriages go bad every day.

We are waiting for the EAD/SSN. Our local Social Security office either didn't know how to do it or didn't want to but they said the couldn't with the I-94. They acted like they'd never heard of such a thing. It's a shame because he could have had his driver's license months ago if he'd had his Social Security number. We married in mid April but still haven't received an interview letter for his AOS. Congratulations on the interview date!

I don't see why not, you could start all the processes to coincide with his 18th birthday ...   
 
How long did it take for your husband to complete the visa process at the embassy (medical, paying visa fee, scheduling the interview, etc)  ?   That should be a good gauge.   

Thank you, everyone!

Yup. The only caveat I see is he will have to wait until either his EAD/AP card or GC is approved in order to work in the US and travel outside the US.

Correct,  it is one of those rare situations where a k1 will be more advantageous than an IR

OP's step son should interview for the K-2 follow to join between October and February. OP's husband's K-1 was issued on 2019-02-15: https://www.visajourney.com/timeline/profile.php?id=290664
https://www.uscis.gov/family/family-us-citizens/visas-fiancees-us-citizens "If your fiancé(e) has a child who is under 21 and unmarried, the child may be eligible to come to the United States on a K-2 nonimmigrant visa."

Besides common knowledge,  I have a for sure answer.

Look under children of fiancee. 
 
 

My first thought was the FOLLOW-TO-JOIN instead of an IR visa... if it could be completed in time.   BUT ...
 
I found this regarding the K-2.    (they could contact their embassy to verify)     For the IR visa his age is not an issue.
 
Minor children identified on the approved I-129F petition may follow to join their petitioned parent. However, such follow-to-join K2 visas can only be issued within one year from the time the parent was issued a K1 visa. After one (1) year, they no longer derive immigration benefits from the I-129F petition and you or your spouse must file an immediate relative or second preference petition for them to qualify again

You can file the I-130 today as his USC stepmother.  It will take about a year for him to get an immigration visa and an instant green card when he enters the US (no need to adjust status).  He will be 18 when he interviews and he will not need his mother's permission since he will be an adult.  

On the plus side, at least in theory EAD and AP processing times have gone down (at least, they're still saying 2.5 to 5 months at NBC, and after a week, that's hopefully not a mistake).

FYI - you can find the field office for your area here: https://www.uscis.gov/about-us/find-uscis-office/field-offices (search by zip code)
and then look up I-485 processing times for that office here: https://egov.uscis.gov/processing-times/
 
The Norfolk, VA office lists an 8 - 17.5 month range for family-based AOS. Many AOS from K-1 applications do come in before the "minimum" for the field office, but 8 months from May 2019 would put you into 2020.

Ready to be scheduled is not the same as having the interview scheduled. It means that the case is in line for when slots open.
it can take a while before it is in fact scheduled and that’s when you’ll get a notice to appear for interview by mail.
check processing times for your local field office

Sorry I assumed you meant Panel Physician when you said CS. After reading further you have not completed your vaccines overseas.
 
As per submitting anything from your overseas medical. Nothing you have would be valid as your Interviewing officer would obtain your overseas medical from your file at your interview. The valid part would be in your sealed envelope and now waiting for you in your A-file.
You will need to bring the new I693 with the new vaccines transcribed on it to your interview.

No they will not reject because they will process as credit 

Per the USCIS web site:
"Depending on the form you are submitting, you may pay your fees online using a credit/debit card or bank withdrawal; by mail by card or check; or in person at a USCIS field office. You must submit the correct fees or we will reject your form."

I am not saying that I am correct in this.  I'm just relaying the experience that a close friend from England had.  She is a teacher.  There are a few companies that 'translate' transcripts, not in the sense of language translation but more of an evaluation.  She had some problems because her college had changed names and they did not have official transcripts the way American colleges do.  For example, there was nowhere she could have a paper with every class she took and the grade she earned or the description of the class.  Finally, she got someone from the former college to send the list of the classes a student had to have for that degree and a description of the classes (an official signature, of course)  The translating company looked at each class and compared it to what a student has to have to get the degree here.  So, she did have to take some extra classes that she felt she didn't need. I had the opposite experience when I worked for the British Council.  They didn't tell me until i had finished the job and then paid me at a lower level saying that my MA wasn't as good as the British one. Countries seem to be arrogant about their degrees as if someone from another country couldn't possibly be as qualified and if they can pay you at a lower rate, they will do it.  They were very keen to hire me for my degrees and qualifications but not to pay me. It could actually depend upon the company that wants to hire you. I wish i could be of more help but hopefully I've given you something you can use. It could be completely different in your profession.  Good luck.
