OCU is regarded as a good college in the OK city and surroundung areas. It is located in the heart of Oklahoma city, about half an hour from both OU and UCO. There are quite a few Nepalese students attending this college and as you might also know there are a lot of Nepalese in UCO, so it will not be any difficult for you if you're thinking of getting some help from the community. You can get hold of them through UCO and OCU website>international students center. And they are very helpful to newcomers to their colleges and their cities. Living expense wise, it is very reasonable to live in OKC and Edmond, where UCO is located. However, it is widely hear aajkaal that getting offcampus jobs (cash jobs) in the Edmond and OKC is pretty much hard and risky. Anways, good luck to you bro!
