Well...adaptation can vary greatly from a country to another, and sometimes we can have unexpected surprises. I am not talking about things such as timezone since after a few travels you will be able to adapt in two days.
Having moved around the EU and being Chinese, I thought that my stomach was prepared to anything...that was until I had my first burger in the US...at first it went through without any problem but I'll always remember the night I spent after that...
As a matter of fact, my stomach wasn't used to the American beef and it took me a few months to get used to it.
Now, there are also other things that you may not think about and food is only one of them.
One of the greatest issues I have encountered has been regarding finances. Indeed, studying abroad is costly and I ended up a few times skipping a lunch or a dinner because I had to pay my rent. Before you engage in a study abroad program, you should try and see if you can obtain enough financial support (grants, scholarship, etc) and plan to find a part time job if need be (which is gonna be twice harder since you will feel much more tired from using a foreign language all day).
I don't know the programs in Texas but here in Louisiana, they do not have many exchanges. I had to go through quite a few private programs before finding something that was quite good.
Also, in EU, we can apply to a special type of placement that last from 6 month to 2 years during which we work for a company in a foreign country somewhere in the world.
Such things certainly exist in the US and although most require at least a Masters, some probably hire at the associate level.
Anyway once again, if you have the opportunity and the motivation to engage in a study abroad program, I highly recommend you to do it. Such experiences have been among the most enjoyable I have had so far and I still remember each of them as my dearest memories.
