South America - US Dual Citizen - Argentina & Brazil Customs

I am a US citizen and am headed to Argentina on Sunday for a week or so. As background, I hold a passport from Germany as well. They are both brand-new and neither have any stamps in them yet.

My current itinerary takes me from the US --> Argentina, and then Argentina --> US. I am considering a stop-over for a few days in Brazil, but I do not have enough time in advance to get a Brazilian visa before departing, so was considering using my German passport instead. I was wondering whether this will cause my problems at the borders. My current thinking is that I could:

- Leave US on a US Passport/Enter Argentina on a German Passport
- Leave Argentina on a German Passport/Enter Brazil on a German Passport
- Leave Brazil on a German Passport/Enter US on a US Passport

Does anyone have any experience traveling through South America (particularly Argentina and Brazil) and using multiple passports? Wondering if using multiple passports in this fashion is going to raise eyebrows or cause me grief at immigration in the US, Argentina, or Brazil.

Honestly, I am going for vacation and the last thing I want to do is be nervous about having problems at Immigration - I just want to enjoy the vacation, so if this is going to be problematic I will just skip the Brazil portion all together.

Thanks in advance!

That's fine for most. Enjoy your trip without any further worry.

US-EU Schengen zone nationals do exactly that kind of thing, primarily to save money and/or get around the hassle of dealing with a receiving country's embassy/consulate.

Multiple passports is the common denominator in Argentina and Brazil - not an issue

I didn't go to Brazil but still, you might find this interesting.

I just returned from EZE last week. Dual US/EU national, carrying both valid passports.

It was my original intention to use my US passport and pay the $140 reciprocity fee. I lined up with US passport in hand and credit card at the ready. The Argentine Immigration officer asked me if I possessed another passport and when I said yes, she asked from where, I said EU nation, asked is it valid, I said yes, she said, go over there, don't pay the fee. She waved me away. None of this was proposed or initiated by me.

I followed the official's suggestion and went to the other line and used my EU passport. Stamped in for 90 days at no cost.

When I returned stateside I entered on my US passport. I thought I would need to explain why no Argentine stamp/visa in my US passport. But the official made no comment on the stamp situation, actually, this officer didn't even ask where I'd been. He didn't ask for other passports/nationalities or anything else, just about my job and then stamped me through.

Obviously in ease, speed and other measures, the EZE experience is the inverse of what I expect and receive from the notorious Immigration Canada :(

Use your Kraut Reisepass...... forget the gringo version and save the fees......

Had a buddy come down last year from the states with no issues. Entered and left Chile on his Irish documents, back into the US on his American.
