Has anyone used the this service? Well I just did, their customer service is ok and it might be a good option if you need to get your passport within a week or two. They charge about $125 and you have to pay the standard fee for US State Department. For me it was another $189. If you don’t need your passport in quickly, just skip paying the additional fee.
