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 am exploring an option to move to Canada temporarily in order to save my Canadian PR. My PD date is March 2012 and have an approved I140. Currently my H1B extension based on approved I140 is in process and hopefully it shall come soon and will be good till Feb 2022. Plan is to move to Canada after H1B approval and H1B visa stamping from India. <br>
Questions<br>
1. If Priority date becomes current during my stay in Canada then what are my options.<br>
2. If Priority date does not become current and I tried to enter US after staying for more than year outside US. Two situation could occur H1B extension (I797) is still valid (before Feb 2022). Will I be challenged at port of entry whether i am going to perform the same duties as mentioned in I-129.<br>
3. To convince them on job responsibilities will the letter from employer be sufficient Or need something else?<br>
4. Recent pay stubs shall also be helpful to prove my continue employment with my same employer ?
5. H-1B extension (I-797) is expired (after Feb 2022) OR because of some reason I have to file new H-1B extension to enter Can i use my approved I-140 to file new H-1B extension(or claim the H-1B period) and that will be cap exempt ? OR I have to file new H-1B petition and re-enter the lottery.

1. Am I allowed to open a corporation and run a business on GC-EAD?<br>
2. If no, can I still work on a 1099 and file my taxes or do I have to be on a W-2 for an employer?

1. I have approved I-140, on 7th yr of extension and my current H1B Visa and I-94 valid with emp A until dec 31,2018 based on my latest approval I received in Nov 1st week.
I have another 1 month to apply for an extension and I am requesting my employer to apply in premium processing.

1)If my extension is applied in Premium before I-94 expiration but pending beyond my expiration date 12/31/2018,
I will be 'out of status' even though 'authorized to stay' until decision is made. Is this correct that this may affect my future H1bs in case it is denied
and attract NTA(notice to appear) in future because of my 'out of status' from date of expiration to date of denial or while leaving the country upon denial.<br>
2. Is it better if I leave the country on the last day of my I-94 expiration(Dec 31, 2018) while my H1B extension is pending in order to avoid 'out of status' or 'unlawful presence' scenarios by staying here.
If I leave the country while extension is pending in above scenario, is it possible for me to go for consular processing, get VISA stamped after it is approved and enter the US legally?
or
is h1b extension is considered as abandoned?

I applied for EB3 in 2011 and port to EB2, now EB3 dates are moving forward and if it reach to my priority date am I still eligible for EB3 as I initially applied for or do I need to downgrade to EB3. Will there be any questions raised?
