If the child is properly adopted in India, the child is your child for purposes of a nonimmigrant visa. You can seek an H4 for the child if you are on H1 or another nonimmigrant status which allows for derivative visa. If you are not in a valid nonimmigrant status, you will have to wait until you are adjusted your status to that of the LPR before you would be able to seek follow to join pettion for the child. The USCIS form will be I-824. These are your option.
