Translation of engineering in Spanish

In the early morning, before going to the airport we went to the travel office of the Vietnamese airline company to avoid about possible problems with the entry. They assured us that everything was fine.
Oh great, i want to learn English with you. It am so happy that you will help me. Thank you lots and lots. Where do you live? I live in Switzerland, near the city of Basel. I'm a student of economics.
In the late afternoon we took a taxi back to Cusco, which we shared with a nice Spanish couple. My wife who was mainly concerned with our sleeping conditions took the address of their hotel.
