I am a student and I am joining University of South Alabama for my graduate in civil engineering. Well I have admitted and now I am in USA. I have to register for the course sooner but I am totally lost in choosing the major for the field. Can anyone please help me with the major I can choose. Well Structure is something I dont want to do. The other options are Environment, Water Resource, Transportation and Geology. Please someone advise me the major which I can choose so that I dont end up thinking I chose the wrong major. Please suggest me which major can land me with a good prospective degree so that I may get a good job in USA. Also please advise me whether GIS is good for USA or not. Please help me because I am totally lost.

Thank you in Advance.
