Hi, newbie here. Here's my situation. I've recently become a US citizen and will be petitioning my parents to come over to the US. Once they get a chance to come over, are they required to stay at the residence of the petitioner? Can they stay at another location (ex: at an aunt's place that is in a different state) while the process is not yet complete? They don't like the winters here in the Northeast so they're thinking of staying in California. Hoping for feedback. Thanks!
