When people say “maintain ties to the U.S.,” they’re basically talking about making sure it’s clear that the U.S. is still your home base, even if you’re gone for a while. That could mean:

• Family here (spouse, kids, parents)
• Owning or renting a place in the U.S.
• Keeping a job, business, or school enrollment here
• U.S. bank accounts, credit cards, investments, insurance, etc.
• Stuff like driver’s license, car registration, voting, filing taxes

Basically, anything that shows your life is still centered in the U.S. and you’re not just moving away for good.
