... they still might not let you in, and after you've let out your house for a year and made all your plans ....
Didn't mean to scare you; It's highly unlikely that they wouldn't let you in. Just my standard caveat, because we see so many folks say that they have their visa and, unlike you, don't realize it doesn't guarantee entry.
A couple of years ago, our son and daughter-in-law came to visit from the UK, something they've done on a number of occasions. Because of work schedules, our DIL came a couple of weeks earlier than our son. During the routine Q & A on arrival (why are you here? where will you stay? how long will you be here? etc), she casually mentioned that her other half would be joining her in a couple of weeks; That sent up a red flag and made the CBP officer suspicious, leading to a barrage of additional questions.
We've heard a few horror stories here but, over the 40 or so years I've traveled extensively to and from the US, as a foreign (UK) national, a legal US resident, and as a US citizen, I've never experienced a problem personally. I'm always polite and non-confrontational, answer the questions I'm asked, and don't volunteer unnecessary information. One time, they even let me in when I'd mislaid my passport (see below).
Here's the story, from an earlier message of mine, but don't try this intentionally; The rules for entering the US have changed since this happened.
We docked at the 'customs dock' in San Diego aboard our own boat, standard protocol after returning from Mexico. We'd called ahead to request CBP agents to come down from the airport to check us out. When the agents came aboard, I couldn't find our passports because I'd put them in a 'safe' place when we left home 3 months earlier. All our (US-born) passengers were OK but, because of my 'accent', one of the agents insisted on seeing either a US birth certificate or a passport from me.
I was sweating, but he then asked for my drivers license, called his office on the phone, and said "You're good; You're in our computer and have been in and out of the US so many times over the years, we know who you are. Have a nice day". WHEW!
Meanwhile, I explained that Chris wasn't feeling well and was laying on the bed in the forward berth. They didn't ask for her passport, preferring not to disturb her.
