General Nonimmigrant Visa

My wife is on TN (expiry date : Oct/2019) and my two kids are on her TN as TD visa holders (expiry date : Oct/2019).
I am on TN Visa (expiry date : Apr/2019) and my perm just got approved and am in the process of simultaneously activating my earlier inactivated H1B visa and filing the I-140 with the hope after few months down I will be with an approved I-140 and H1B.
My wife wants to stay on TN (kids on TD) as long as possible because the employer doesn't want to sponsor H1B and moving to H4 EAD doesn't look like a smart option now due to uncertainty surrounding H4-EAD's.

I'm completing 6 years on H1B on 14-Jan-2018 and I have a visa stamped with the same date from my previous employer on my passport. When I changed job on 24-Jan-2017 I received an approved I-797 with an expiry date of 14-Mar-2019. I'm not sure if there was an error from the employer or attorney while filing or while approving the application. Now I have an approved I-797 with an additional year which would mean 7 years on H1B at a stretch. I'm planning to visit India with my wife (on H4 visa) next month for a couple of weeks and return back before the visa expires on my passport. Also, I'm thinking of not getting the new visa stamped on my passport and just show the approved I-797 to the officer while entering the US. Do you see any problem or issues if I do this?

I entered the US in 2014 on L1A, then changed employer mid-2015 on H1(previously held petition). In 2017 again changed employer in a role equivalent to International Manager. Can my current employer file my Green Card under EB1 category?

I have read that in some cases of H1B as follows "They had H1 petition and H1B visa was stamped in 2012 but they never traveled to the US on that. And when a new employer applied for a cap-exempt H1B petition in 2017 they got it approved with change of status to H1 in May 2017...Whereas in my case I also didn't use this H1B visa and I even didn't travel to US i.e. My employer filed H1B in 2016 which got approved in Sep 2016 and after my resignation, they revoked H1B in Nov 2016 (which is > OCt, 1 2016), but I got a Denial. When contacted few attorneys they said I may get "Approvals" Or "Deny" in such cases, nowadays its more of details saying I am NOT cap exempt?

I'm an Indian citizen on an H1B Visa. I'm an engineer. My Green Card is being processed and my I-140 . Being an EB-2 category I"m assuming that it is going to take anywhere between 5-8 years before I get my green card. The Situation: I'm planning on taking a work break for about 6 months to 1 year and do a few things that I've wanted to do but have been pushing indefinitely (like volunteering with a non-profit, spending time with my family, exploring options to start my own startup etc). I'm assuming there are 2 scenarios here - 1. My company gives me a sabbatical leave - I can leave the country for a year and come back and rejoin them. 2. My company refuses a sabbatical and I have to quit - In this scenario, I'm not sure what I should do in order to be able to come back after my break and still be able to work for any company? I would really appreciate your insights on this situation and would be glad to accept any pointers from you to research this further.

In case of H1 transfer denied what other options one can have ? [provide that has 140 approved since many years]<br>
1. Can new H1 transfer with new employer can be initiated ? 2. Can one can apply for B1 [Visitor Visa] and remain in USA for valid period ?

1. My H1B is valid until 23-Aug'18. I am planning to submit visa extension request on Mar'18. let's assume if USCIS reject my extension request in Apr'18, then, in that case, can I stay till 23-Aug'18 as per initial approval or rejection will supersede and I have to level immediately (within 60 days of time from denial date)<br>
2. Does H-1B extension denial invalidate an existing H-1B?
