User Statements  P4: “When I first arrived to US, my highest priority was getting a good accommodation. I searched a lot for Chinese renters in College Park. If the renter is Chinese, it would be easier for me to get a Chinese roommate. And if my roommate is Chinese, we can cook Chinese food together!”  P7: “Whenever I need any information, I ask my friends. If they can’t help, I try to find it on Google”.  P9: “My dream map system would just show me everything around me that I need”.

User Statements  P3: “I’m a pure vegetarian. I always consulted with my friend about vegetarian food. He taught me how to tell the restaurant servers to prepare the food, like what to put and what not”.  P3: “During my initial days in US, I didn’t watch many movies. I didn’t attend any entertainment events. I was most concerned about exploring this area, transportation, and food options”.  P1: “If the question is specific to me, I would be happy to answer that. But if it’s generic, I think anyone can answer that”.

User Statements  P8: “I’m afraid if I share the information publicly on Facebook, people will irritate me with more questions”.  P5: “Once we went to an Indian restaurant but didn’t know that they have a buffet until we finished. Their website didn’t show this information either. Later my friends told me about it”.  P8: “I went to Shoppers and got some vegetables. At the time of checkout, I wasn’t sure about the English names of some vegetables. I had to call the attendant”.
