Clearing US Custom at YUL - EU passport
 

Hello,

Apologies if I missed the info in another thread.

[edit: my in laws] need to clear US Custom at YUL on a Saturday in October for a 11:30am United flight to EWR.
[edit: my in laws] have a EU passport and my 2 kids with me [their 2 grand kids, with French passports too].
can you confirm this is possible? How much time should it take?

Bonus question: is a 45 min connecting window reasonable at EWR, assuming customs have been cleared, with a change of terminal?

Thanks in advance!
Ben.

Do your children have passports too? If they are traveling without their other parent, you might want to have a notarized letter of permission from the other parent. (If the other parent is deceased, then a certified copy of the death certificate might be good to have.)

Bonus answer: With a change of terminal at EWR, I would say that 45 minutes is very tight. If you are able to access an airside connecting bus, it's possible if everything works out just right (and any checked baggage is checked through to your final destination). If, for any reason, you must go landside, take the AirTrain, and re-clear TSA security in your second terminal at EWR, I'd say that you're likely to misconnect.

sorry, i tried to simplify my question and I realize I shouldn’t have. It’s my in-laws flying with my kids. My wife and I won’t be there.
will they require some kind of notarized letter as well?

I can't say that it's required, but I think that it would be wise for the grandparents to have in their possession a notarized letter of permission from both you and your wife. You might find this information posted by the Canadian government to be helpful:

https://travel.gc.ca/travelling/children/consent-letter

("Consent letter for children travelling outside Canada")

If you need English-language notary service in your home country, it should be available at a Canadian or U.S. consulate.

Canada usually doesn’t care as much about letter than USA does. Give them a notarized letter signed by both parents.

OP: Note also that your children, since they are not traveling on Canadian passports, will need to have approved ESTAs in order to be admitted to the U.S.

I would say you won't need it. I've entered Canada alone as a minor alone quite a few times and I have never been asked for a consent letter

The question was not about entering Canada, but about entering the US.

You still need to pass through Canada Customs for ITI connections at YUL, meaning it is a possibility that CBSA might ask for it
