Try Capital One! They offer not only security cards but also certain cards for no credit foreigners who want to build up their credit scores :D I've got mine few months ago with 2000 limit and I am very satisfied with it. For your credit scores, it said you have to wait couple months (6+) in order to have your credit scores built and available to be checked by third parties. So just be patient and get yourself a credit card first :D

capital one, 还能免费看信用分数

跟銀行商量，放1000美金做guarentee,申請1000刀以內限額的信用卡，努力把信用卡utility保持在35以下，一定一定按時還錢，熬幾個月就可以看到還不錯的分數了
