Would my husband's gas connection papers be valid as my address proof?
yes, this may be considered but to be on safe side try to open an account facilitating either or survivor or joint mode of operations. since you already have gas connection paper so it wont take him to open an account more than 1 day. however, bank accounts less than an year are not considered but along with other documents with his name would suffice their need. remember their discretion is final so describe you issue in best possible manner if needed so that they may help you out of this situation. trust me those set of intellectual people understand the common concerns and they wish to help each individual. just make a move and youre all done with your passport renewal. good luck thank you.
