The letter states my biometric schedule b4 and below it was rescheduling appointment and there was an instructions that we need to send thsi letter to the local office so we did it we sent the letter february 01,2010 and my local office which is san antonio received my letter feb.2, 2010 but until now they didnt send me anything yet....do i need to start making worried now? or i just wait for it? i have a fear now becoz when we filed my aos we just keep waitng and waiting and we dont have any idea about the undeliverable letter of mine until i called the USCIS to update my status....any advice pls????i need an appointment soon coz they gonna move my husband to other station hes active duty in the militar ryt now so absolutely we will be moving to other states....answers are highly appreciated
