Travelling on two passports questions
 

Hello all,
I'm wondering if you could help me with something. I am a dual us/uk citizen and i live in the uk.
In June I am traveling to costa rica to visit my aunt. I am then travelling to Boston in the USA to see the rest of the family before heading home.
I am just checking to see what passports i should use. I know that upon leaving the EU I must use my UK passport and entering and leaving the USA it must be my US passport.
I am wondering if, upon entering Costa Rica, I should switch to my USA passport as I will have to use the USA passport going from CR to the USA, if they stamp it etc....I'm not sure if I could switch passports mid trip though
Can anyone shed any light on this?
Thanks!

When entering the US you only show your passport to the US CBP and must show your US passport.

When leaving the US you only show your passport to the TSA and airline staff, who will compare it to your airline boarding pass. The names should match.

Don't know about entering and leaving Costa Rica. Do you need a visa to visit there for either or both of you nationalities?

Regards, JEff

I would think that you would use whichever passport is most advantageous to you in CR, in terms of visa requirements and entry times.

Is it ever a problem? Can't you just wave them one by one until they are happy?

I don't need a visa of or eit,her nationality. Would I get in to trouble for entering coasta rica on the us passport? As ill be leaving on that one and obviously they'll want to see the stamps etc to assess how long I've been there when I leave....

I highly doubt that.

Is that correct?

No, the UK doesn't care. ... Per the OP's questions, it is likely that they can pack their British passport away and only pull it out for a speedy passage through immigration coming back into the UK.

That's what I thought. I've exited (and entered) the UK on non-UK passports even though I'm a UKC.
