traveling with us passport and your native country's passport in other countries

[ketanco]

i will get a us citizenship soon and i have two questions. when i will travel to my native country i will enter with that passport. not usa passport.

1)now assume that i want to travel to a third country from my native country. the third country does not ask visa from usa, but it asks visa from my native country. so when i leave my native country on a flight to the third country, would it be a problem when i enter to the third country and can i not use usa passport there to get in because i will have used my native passport upon leaving my native country? how does this work? because i will use my native country's passport when i leave my native country.

2) say i go to another country, from my native country, call it fourth. this one asks visa from usa citizens, but not from my native country. so when i travel from and to my native country i just use my native country's passport. but in this case the question is, when i return to usa, to the countries visited list that you have to fill in, if i write that country, there would be no record of it on my usa passport. how does this work?

i appreciate experiences and references from regulations

Use your US passport to leave and enter US. Your previous passport (if Valid) to enter native country and for any other country use US passport when leaving your native country and enter 3rd country.

Check if your native country is in the list of countries where dual citizenship / passport is allowed.
