Congratulation Micky-Micky. Being a Nepali student at Texas Tech it is indeed a good news that you are going to join our community. I think it doesn't depend which department you are attending as long as you can fulfill your dreams. I don't know from where Yesai calculated the number of students and come with the point that half of the students are from plant and soil science. Texas Tech has around 30 Nepali students and they belongs to different departments like Plant and Soil Sciences, Computer Sciences, Civil, Industrial, Electrical, Petroleum Engineering, Biology, Agricultural economics, Maths etc. I hope it will be good for you if you are also joining one of these departments. For contacts you can go to website provided by Yesai and then mail the members.

Have a nice remaining days in Nepal. Enjoy.
