Recently got SSN,how to build credit
I am in US since sept'06 on h4.I recently got my SSN.I opened a bank a/c with BOA in feb. this yr and have been using a secure Credit card since then,making full payments and using about 75% of credit limit. I do not have any credit file yet(tried to pull credit report but denied from all 3 bureaus).I am being denied by citibank,amex and others for unsecured CCs due to no credit history.How much time does it take for BOA to usually report my secure CC to credit bureaus?when can I expect to have a credit file?Also,is there any way to build the credit faster or is there any major unsecure CC thatI can get?(P.S.: I was never a student here,so I can't apply student CCs).thanks in advance
