I recently submitted a DS160 application for a J1 visa, after submitting i starting compliling all of the required documents to take to the interview. Upon doing this I realised that I had not attached a signed version of my DS2019 (but just the form itself). I am aware that there is no way to go in and change this on the application however will this cause me a problem in my visa appointment? Will this prevent me from getting my visa or cause a visa refusal.
