I am a US citizen. My parents (father 72 y and mother 65y) have a valid multiple entry visit visa to USA issued in 2012 and valid till 2022. They used to make short visits to USA every year till 2016 with duration of stay averaging around 55 days each year. After my father’s retirement in April 2017 they have settled down in India.
During their visit in June 2017 they stayed here for just under 6 months (174 days). They visited this year as well for about 173 days, arriving in SFO in June 2018. Upon their arrival at SFO, the CBP officer cautioned that the 6 month stay is not acceptable each time they visit, perhaps they will be given only 1 month stay during their next visit and that they should apply for green card if they wish to stay longer.

Based on your expertise, we would appreciate if you could let us know whether there is a possibility that the CBP officer would have placed an adverse remark/ comment on their system and would enforce a short stay of 1-2 months during their next visit (tentatively in June 2019). Being aged, they are more comfortable with making 6 months visits on multiple entry visa rather than staying for longer periods in USA to keep Green Card valid.

I had EB-2 I-140 with PD of March 2017 , My EB-1 I-140 is Aug 2018. My attorney has filed for amendment of priority date - How this works , will they open the case again ?
How long will it take to get the amended I-140 with old priority date.

In Summary, <br>
* I worked for the same Company from 2004 to 2014 (2004 - 2011 in US on H1B, and 2011-2014 in India)<br>
* BUT, after Green card, I did not work for the Company in US.<br>
* I don't have even a single paycheck from US Company after receiving GC.<br>
* Since then, I have been working in a job with same job description that my GC was filed for.<br>
* All other history is clean. I have two US born children, Always paid taxes on time, no legal cases.<br>

I heard from reliable sources that under current circumstances, my case will be marked as fraud and there is a 99% chance that they will revoke my GC and deport me, as I didn't stay with the employer that sponsored my GC.
<br>
Questions<br>
* Should I be really concerned?<br>
* What are my options?<br>
* I have the option of going back to the same employer now. Does that help?<br>
* If my wife applies for Naturalization instead of me, is that going to be any different?
