I have been residing outside of the US, but have used a New York State address for certain purposes. I now intend to move back to that same address. I would like to buy health insurance soon after I arrive. According to healthcare.gov,
Most health plans sold outside Open Enrollment don’t qualify as minimum essential coverage.
The only way you can enroll in a health plan through the Marketplace outside Open Enrollment is if you qualify for a Special Enrollment Period.
One of the "Qualifying Life Events" for a Special Enrollment Period listed at nystateofhealth.ny.gov [WARNING: site access blocked to non-US IPs] is a
Permanent move to NY, or permanent move from one county to another within NY
Does my move count as a move to NY, because I am truly moving and changing my residence? Or do I not get a Special Enrollment Period, because I'm moving to the same county that I already had an address in?
According to the Health Reform FAQs of kff.org,
Most states consider you a resident if you intend to make that state your permanent home. So-called “snowbirds” may own a second home and live part of the year in another state, but their official state of residence is where they spend most of the year, where they pay taxes, where they register their cars, or are registered to vote.
Instead of a second US state, I have been living in another country, so I pay taxes and have registered a car in New York State, even though I spend almost no time there.
