Questions about entering the US after travelling with 2 passports

[whatever1111 0]

I have a few questions about a trip I'm planning to make to the US soon.

The background:
I recently moved to Mexico (where I am living now) from the UK. I have both Mexican and British citizenships.
On my way to Mexico from UK, I stopped in America as a tourist for 9 days, entering the US with my British passport unde the Visa waiver program.

I then continued onwards to Mexico using my Mexican passport.
I've been living in Mexico now for over 100 days (around 4 months).

I'm now planning to go visit the US soon, as a toursit for 2 weeks, using my British passport again.

As I understand it, under the Visa Waiver program im only allowed 90 days in North America, which includes Mexico. Since I've been living in Mexico for so long, I'm not sure if America will think I have 'overstayed' the conditions of the VWP as a UK citizen - despite my having Mexican citizenship.

My questions are:
Will be able allowed to go into America as a tourist again using my UK passport?
Will they accuse me of never officially having left North America after 90 days? Or will I be excempt from this rule because of travelling under my Mexican nationality?

And does the US have a record of me officially exiting the US, if I arrived into their country on a UK passport and then exited on a flight where I gave details of my Mexican passport?

Just present both passports at the POE as evidence that you reside in Mexico and that you didnt simply go to Mexico to get around the 90-day limitation. You should be OK.

So when you exited the US you didn't show your UK passport at all?

No, I don't think I did, as far as I remember. The US apparently does not have departure immigration checks at airports, at least not the way other countries do (though I did not know this at the time).

I don't recall exactly what the procedure was, but I think all I had to do was use my Mexican passport that I used to book the airplane ticket to check in, and then get on the plane to Mexico, without a face-to-face immigration check.

It would have probably been a lot smarter if I had booked my plane ticket using my UK passport, and then just showed the Mexican passport to Mexican authorities after landing in Mexico. But I fly a lot, and I'm used to booking flights with the passport I need to enter the country (since the airline can deny you boarding if they don't think you'll be accepted into a country). And usually, the immigration checks by the country I'm leaving give me a chance to clear anything up. Having said that, I really didn't think this through at the time, and I feel dumb that I didn't realize I was potentially getting into a situation where America might think I never left.

I'm afraid they might think I overstayed, and they might not let me visit again. I'm not sure how to correct this, if they don't have a record of me having officially left the country.

US does not have any immigration when you leave - they do get records from the airline..

But do you have any stamp on arrival into Mexico?
