B-2 Visa

Spoken to the current employer's attorney on Tourist visa , they replied its not a correct path moreover it takes much proofs to tell USCIS i was on H1b working for employer and then changing to visitors and then after certain period of time when i find a project, changing it back (i.e applying) to h1 makes this case more complex.

I am planning to sponsor Visitor Visa for my sister,she was diagnosed with Down syndrome when she was 1 year and she is now 45 yrs old.
Considering her condition, i would like to know what additional documentation is required for visitor Visa B1/B2 apart from I130, letters to consulate & bank statements.

My father recently renewed his B2 Tourist Visa - and was given the 10-YR Multiple entry visa. He is currently visiting USA and his current I 94 expires in end of May 2019. Due to some medical issues - we were contemplating about requesting a 2 to 3 months extension for his stay - if possible. Would you necessarily have to provide an evidence in the form of a return ticket (about 3 months hence from end of May 2019) - to prove that he indeed intends to go back

1. I am currently in H1-B more than 10 years in the USA and I have approved I-140 priority date Mar 2011 - EB2. My current employment is getting over in 3 weeks. And my current H1-B and I-94 expires in mid-August 2019. My question is if I am not able to find another job within my H1-B and I-94 expires on Mid August 2019. What are the options available for me to legally stay in the USA after my H1-B and I-94 expires? I have own house. Is there an exceptional case we can file GC EAD? <br>

2. Without a job how many days i can stay in USA before my I-94 expires using I-140?

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.
