He teaches in a university and he can decide which semesters he wants to teach basically. For example, he can take the Fall semester off and come to the US.
Given that both his kids are in the US, they have been contemplating the GC option for a while. Without getting into too much detail about our situation, I wanted to know having been given only 3 months stay this time, can they apply for GC and stay their full 6 months.
Thanks for your response.
It will also make their intention of coming to the US for about 6 months/year easier to manage.
