Hi:
I am a 4th year Iranian Ph.D. student and after visiting my family this year and applying again to re-enter US, I was refused to receive my visa under section 212(a)(3)i and want to apply again for visa since I am sure this is a misunderstanding of my research. My questions are:
1) Is this a permanent rejection or I can apply again?
2) what can I do to help my case and overcome the refusal this time?
Thank you so much.
