My wife and I are coming to America later this fall, right when the iPhone 5 should be good and ready. My credit score is close to 790, but she will be entering on an immigrant visa and getting a green card, in other words, she has zero credit history/ties to the US whatsoever. So we know she will need a deposit. As this whole process of obtaining her visa and moving overseas and getting setup/reestablished is a very expensive and hectic time for us, we are kind of curious to know about how much we can expect to pay for a deposit for her? $125, $500, $1000? Or, alternatively, given that I have really excellent credit, could we avoid a deposit altogether if we got some sort of two line family plan under my name? TIA.
