I’m in Cabo. I work for a foreign organization. My Argintinian and German bosses had concerns coming here.
I wouldn’t - unless you are of Arab descent. Then I might have pause.
But are you going to uproot/change your life for a .1% thing?
And I don’t know how they knew - but the Brown professor, for example, had attended a funeral for a terrorist - so they had stuff on her, etc.
Good luck.
My husband was born in a politically inconvenient country. He’s been a naturalized U.S. citizen for 35+ years but I do have a twinge of worry for our two upcoming int’l trips.
I told him if anything happens at the airport then the kids and I don’t know him 
(gallows humor…. my worry level is about 3% which is about what my worry level is with lots of other things these days)
Yes I have some anxiety about my international adopted child visiting her home country this summer.
In any other time in my life, I’d think you were being silly and paranoid, but these times are like no other in my long lifetime.
Saying that, I think you both should be fine and if you’re worried about your phone, maybe turn it off, put it into your carry on luggage and print out a paper ticket. I remember people at my company flying into Hong Kong in 2020 and being forced to turn over their phones for scrutiny. I wonder if we’re turning into that? I’m going to Spain in May, highly tempted to put an offensive screen saver on my phone, just for that remote possibility. 
I would be cautious about what you wear. No hats/shirts with writing on them. Say you’re a Canadian if a stranger asks.
In any other time in my life, I’d think I were being silly and paranoid, but these times are like no other in my long lifetime too! 
Being White European or from a preferred group and from a “respectable” class is no protection.
A German green card holder from NH was flagged for 2015 marijuana consumption (conviction that had been vacated due to law changes), then held and tortured so he would renounce his green card. A French researcher was not allowed to proceed to the conference he was invited to in Houston because (like about 100% French researchers at the moment and about 90% Europeans who pay attention to the US) he had critical posts about the current Administration on his phone, which was seized along with his work laptop and phone. I don’t know whether those were returned.
This ^ is causing tremendous concern in Europe and there were even official diplomatic noises from each country’s Foreign Affairs/Embassy.
Btw the arbitrariness is part of the point.
As a US citizen, you cannot be denied entry into your own country. However if it strikes someone’s fancy, they can hassle you till you are allowed to go through.
Global Entry is a good way to avoid issues.
Many social media offer “temporary” settings where messages older than 90 days are automatically deleted; you can look up key words then delete them. In addition, you can turn your phone off before the return flight/at take off in the Netherlands.
I’ve just come back from international travel - connecting through Canada, so cleared US customs and passport control there. No issues. The worst was that Canadian customs restricted the amount of sea salt we were returning with (we like to bring it home as a souvenir that we know we will use!) and had to dump out most of it. I’m sure it looked odd going through the x-ray, but they opened it and could see it. Didn’t take the whole bag, just restricted the quantity and dumped some out.
I am a little worried about this- I’m going to Italy in June. I’m not as worried about reentry, but I am thinking that eu countries might step up the inconvenience of getting through immigration etc- as retaliation. I think people who are saying they’re not at all worried are naive- times are very scary. I’m still going though 
My MIL always travels to europe with her EU passport and returns with her US one, I never thought a 75 year old would need global entry but we should probably think about it now she she doesnt get flagged
FWIW, between work, friends and family we have people coming and going internationally very regularly (like weekly). I haven’t heard of any issues in our circle, which includes many different ethnic groups, religions, and nationalities.
We visit family in the UK each summer, and I am a bit concerned about this summer’s trip. We all have dual citizenship and enter on our UK passports and return on the US ones, and it sometimes complicates things with airline check in because the system can’t see a clear enter/leave date on just one passport. My main concern is that my husband is a naturalized citizen and my children were born in the UK. In theory, there is zero reason why there should be an issue with reentering the US, but I am definitely paying attention to others’ experiences right now. We have no plans to cancel, but if my husband did not have citizenship and only had a green card still, we likely would.
I’m a dual citizen as well and I’ve been told to stop doing this-well before the current administration-even though I always used to. Use your US passport for entry and leaving unless you’re staying for longer than a tourist or working in the UK. Yes, the entry line is longer but getting flagged is worse.
May I ask where the advice to do this came from? I looked it up years ago and there was something on the UK government site that said once you have a UK passport, you must use it to enter the UK. I know the US is very strict about this and you can get in a lot of trouble if you are eligible for US citizenship and do not enter the US on a US passport. I know the UK isn’t as strict on that but given what I have read, I would be nervous to not follow that.
So I’m Canadian so the advice may be different. If so I’m sorry. But a US Customs agent told me that they needed to see a leave and reentry on the same passport or I was going to be flagged in the system.
My mil also was told this in the eu. That she had to use her eu passport to enter
So here’s what I found on the state department site. Clear as mud!
U.S. nationals, including U.S. dual nationals, must use a U.S. passport to enter and leave the United States. U.S. dual nationals may also be required by the country of their foreign nationality to use that country’s passport to enter and leave that country. Use of the foreign passport to travel to or from a country other than the United States is not inconsistent with U.S. law.
It seems clear.
Use a US passport at all times- except when THE COUNTRY where you hold the second passport requires you to use THEIR passport for entry- in which case, you are not violating US law.
But you can’t use your second passport just for convenience (shorter lines, less scrutiny for duties at custom) if you are entering a country which does not REQUIRE it.
Well, that does confirm my fears that we do get flagged in the system 
I do think legally we are required to use the UK to enter though, so not sure there is a good solution. Between the current political climate happening now and the new ETA required for US citizens entering the UK (which we do not need as UK citizens, but I fear checking in to flights will be weird for us because we don’t have that and the airlines usually want to check us in on the US passports to show we haven’t overstayed in the US)…I am a ball of nerves!
My H is also a dual citizen with a British Commonwealth passport in addition to his US one. H always uses the British one when he travels into the UK or to any British Commonwealth country and has never had a problem with this.
We were told the same thing that we have to come and go with the same passport.
I have dual citizenship but always travel with a US passport so I can stay in line with my H.
