My parents are attending their immigrant visa interview at chennai in the second week of July. They are being sponsored in the family category by my sister who is a US citizen. They have been instructed to submit all the ORIGINALS of the documents. My question is will they return the originals after evaluation ? Or can we submit notorized copies of the originals. The reason is the date of birth certificates of our parents and my sister can’t be obtained again due to some error in the govt office. So we can’t part with the original we have. Appreciate your response if anybody has any knowledge in this regard
