hi i have applied for b1/B2 visa to attend a conference in usa. there is a mistake in filling DS- 160 form. i have entered my mothers new name as written in her passport. my passport has her old name as it was made earlier. i have already taken appointment for visa interview. i dont have much time left to repeat the whole process as i wont be able to attend the conference in that case. do i have any options now? please guide me.............
