Do they spell out the exact weeks with future dates that someone would be present in US while filing part time H1 petition? If it's anot specified, then i believe it won't solve the site visit issue as they could show up any time. If dates explicitly specified, then employee might lose of flexibility of needing to travel additionally at times for any crucial meetings.
But is it really needed to take part time route?
Like one's manager can handle site visits and confirm the employment details on h1 holder's behalf if they are not physically available at the time of visit. I believe being out of country would not put them in violation of their status as they won't be subject to US immigration laws when outside US. One violates their status only if they work from a different location that's not mentioned in the petition within US.
At the border.. is it not like every visit is treated uniquely and then length of previous visit should affect the outcome? Like if one has correct visa class to be employed and a valid offer at the time of entry, why would CBP be bothered?
I don't think they mentioned exact week. They mentioned something like hrs per month. And I think if you want to mention exact travel plans...you can file lca in that way as well. As far as whether it solves site visit problems or what solves site visit problem or employees working outside of US will create problem or not .....it's for you try it out. I think attorneys in our company are insisting on such arrangement just cover their loose ends. At least they have something to stand upon ....if the question comes why is the employee not present on the site as mentioned on the lca. We got site visit for contractor and he was India, after almost five six months another guy came for site visit for the same contractor. By that time he has moved to some other client. All these site visits I guess spooked our HR so they are playing super safe with h1b employees.
I personally don't think it should be problem working and travelling between US and Canada on h1b. There is guy his handle is agrisiva he travelled once a year on h1b to California during summer. But that was in different era. Times have changed a lot so don't go by what has happened in past.
As far as what works on the border or what kind of questions come up during each entry or what can create problems or what will not.....it's for you test it out. CBP I think have all the discretion in the world. Not saying they are nut jobs sitting on the border.....I am just saying have their own method and madness.
Two cases ...one I came to know recently.
Guy lives in Toronto has b2 stamped and old h1b stamped, was driving to see his wife on h1b. Initially was sent to secondary to get new i94, waiting for an hour, questioning moved present job, is he going to come back , old jobs why he doesn't have h4 stamped. Why is he trying to use this old b2 visa. No matter how much he explained he doesnot live in US, he needs to come back to Canada, their insistence was....he should have gone to consulate and gotten h4.
Another one happened in Niagara falls. Couple lives near the border husband works on h1b. One days due to car trouble he asked her to pick him up. She had both b2 and h4 stamped. When she went to border CBP cancelled her h4 saying she is not eligible for h4 as she doesn't stay in US.
