回複：1-2 months earlier, bring all documents which indicate you

Thanks for your response. Do you need to get an employment letter from your employer? When you schedule an appt, do you need to specify what type of visa are you applying for. Actually, I am confused about this. I am having a H-1 visa, so what I need to apply is a visa to enter the US. Is it right? Sorry for these stupid questions, this is the first time for me to do this.
