What are the pro's and con's of moving to the United States (Texas)?

I’ve got an aunt living in Texas and the past weeks I’ve been thinking to myself that after I’m done with college (I’ve got like 1½ years remaining of school) then I would really like to move there and live with her just to get the hang of the country, I’ve only been once to the United States and that was in Washington D.C.

I’m majoring in Business and with emphasis on Economics and Mathematics. In the future I plan on owning either my own online store, be a freelance make up artist/photographer or even working with something involving the fashion industry and also I currently run a fashion blog and hopefully in the near future it will be successful and my job can be combined with it.

I have always wanted to live in other countries and I think me moving to the States would do good things for me, including bettering my English.

So my fellow Flutheries I know I’m only 18 and only have a part time job so of course it will most definitely be a little hard to begin with but otherwise what advice would you give, what to expect from the very beginning of moving out and the coming months?

Thank you in advance.
