OP I will say get more face time in...I, myself is dealing with a high fraud country (Nigeria)...I have been to Nigeria 3 times and plan on attending for the interview. When I sent off my petition, I made sure to frontload with quality evidence...Not so much about the quantity, but the quality and will do the same with the NVC which is known as side loading...Just make sure to gather all your evidence as of now and not wait last minute, but again, get in as much face time as you can and like one suggested, you can even meet in another country for a different scenery..Wishing you luck on your journey!
