Came to the US long time ago on a work visa, became a lawful permanent resident, recently became a citizen. While under a work visa, my parents applied and got a B1/B2 visa, and came to visit multiple times, including after I became a resident. Alas, their B1/B2 visa expired a couple years ago, and they didn't apply for a new one at that time.
So now I am a citizen, and yes, I am absolutely aware my parents could immediately apply for an immigrant visa under IR5 category. Neither one of my parents has any interest at all to immigrate to the US - they're retired, love their house, their neighborhood, they have their own friends and activities in the old country, etc. So applying for an immigrant visa would be absolutely pointless (and costly) - they just want to visit for at most a month, and then back home to keep enjoying retirement.
So that said - I've done my Googling and found divergent opinions on the subject - "It is almost impossible to get a non-immigrant visa for a USC parent, because immigrant intent is assumed and hence immediately DENIED", or "There's no issue at all - matter of fact, it gets immediately approved with zero fuss".
Sooo - has anyone gone through this exact same scenario recently ? How likely or unlikely is for my parents to apply and get approved for a B1/B2 visa, as it successfully happened when I wasn't yet a citizen ?
