I am planning to apply for my fathers GC after my mom passed away a month ago. He can't travel to US right now for a month or 2 due to work issues. I don't want to leave him in India alone for too long. I am aware that there are 2 options, i.e. AOS when he is in US or CP while he is in India. I can apply for CP while he is in India but as I understand that process can take a long time, over a year sometimes. I don't want him to stay alone for that long. If he comes to US in B1 and then If I apply for AOS, I understand that he has to stay for at least 3 months before I can apply for I130/I485. That will be at least 5 months from now. I prefer this option, but my worry is changes in laws that Trump administration might introduce that might complicate sponsoring parents GC in future. Is the worry realistic? I know last year a bill was introduced (which failed) to stop so called chain immigration. And recently there was an article about blocking GC due to 'public charge' rules.
How realistic are these worries?
