AIG has this program targeted at new immigrants to the US, especially those who don't have any credit history. With a sign up fee of 440$, it's supposed to help us to get unsecured credit card, mortgage, car insurance (at decent price), etc.
I'm having trouble deciding whether to opt for this program. What, What are the alternatives? Can I "build credit history" through other means?
Also, how much of a credit history (e.g. in terms of months) would I gain by starting US life with an unsecured card instead of prepaid cards?
