Last days in Missouri

Well it looks like the time for me to leave to Taiwan is rapidly approaching. I still need to get my Visa, thanks to a lack of funds for my passport, this is cutting it to the wire. I have my tickets, my passport will arrive today or tomorrow morning, then it is off to Kansas City to get the Visa. I am wondering if I should bring a gift for Mr. Su, he is my contact at NJIT and had graciously opened his home to me for the first few days of my arrival. I'm pretty sure a gift is warranted, just don't know what it should be. Hopefully I can run down Dr. Hou or Dr. Fang and get there opinion. Well there is not much left for me to write today. I will talk to you guys soon...
