If I'm a citizen and want to sponsor my parents to get green card, do they have to spend 6 months/year in the US? Is there a way around this requirement? Life abroad is better for them so 6 months/year in the US is a lot, but having the flexibility to come and go would be nice without having to deal with visas.
The short answer is no, they do not have to spend at least 6 months a year in the U.S. We have many clients whose parents essentially live in two countries. Certain easy steps just need to be taken in advance.
