Very interesting email from a person who didn’t provide detailed visa interview experience, but information below shows something unique and this is second time I have come across such experience where F1 Visa was stamped in the passport and candidate was asked to come to US Embassy and visa was canceled.
I went visa interview on last week of December 2010.
They issued me F1 visa
I collected it in VFS on next day.
I’m planing to leave on 12 January 2011.
On 6 January 2011 I got a call from embassy that I need to give finger prints again.
I went to embassy on 7th.
But they doesn’t take my finger prints, they interviewed me for 1hr n canceled my visa.
They sent my passport back with canceled stamp on my visa and a refusal paper saying they refused under 214(b).
There was one other time when F1 Visa was canceled due to fake bank statement. Looks like they US embassy found some information about the person after issuing visa or there could be several other reasons to have the person come for interview again and canceling F1 visa that was issued.
