Hello, My sister-in-law has a 10-year tourist visa from Ecuador. We would like her to come visit frequently over the next 10 years but would also like to apply for her Green Card. We understand that she can't wait for AOS while here on a tourist visa because she is not a direct family member as USCIS defines it, but can she still come on her tourist visa with the AOS in process? We know that AOS can take 10+ years so if that jeopardizes here tourist visa we'd really have to consider applying for it since she already has the tourist visa.

My sister-in-law works for a non-profit that is a 501(c)3 in the US but operates in Ecuador. We have invited her here to the US and would like to apply for a religious visa exemption. Her purpose in the states would be to volunteer/work at schools and daycares to grow in her knowledge and ultimately be able to better serve the nonprofit. She currently has a 10-year tourist visa. We were told to invite her here for 3-4 months, then apply for the religious visa. The nonprofit would be the sponsoring organization, but since she would be volunteering, she would not technically work here or for the organization. Is this possible? Can anyone provide any guidance/assistance on how best to achieve this? She is also the sister of my wife so we could apply for her green card but she can't wait here while it is processed so we prefer the religious visa.
