The visa has come through! I went to Dallas today and got it finished. Thank God. I tried to also go by the LST offices in Bedford (which is somewhat on the way between Dallas and Stephenville), but my directions were not sufficient and after an hour and a half of driving up and down Airport Freeway without finding the office, I headed back to my brother and sister-in-law's house.

Looking back on the passed couple of days I'm kind of impressed with myself; there are lots of things I can do I didn't know I could, like:
Take care of a car (I put water in my radiator cause I was overheating, added a quart of oil cause I was low, and added air to my tires which were only at half the air pressure they were supposed to be at (yikes)).
Drive in big city, rush hour traffic when I don't even know where I'm going (which I did through Dallas twice and through which I discovered that intense classical music helps me drive).
I can go to a city I don't know all by myself and figure out where and how to get important documents processed (which is what I did with my visa today).
Not to say that these things were not accomplished without pointers from other people and lots of help from God, but it's still neat to find out that I have it in me to do all those things, and I thank God for having equiped me with the knowledge and gumption to do them; it is truly amazing how God makes you ready and then leads you through everything he puts before you to face.
