El Salvador I-212 Waiver

[Teutonic_rider 0]

My Fiancee was sent back to El Salvador upon reentry with a valid B-1/B-2 visa. Why this happened remains a mystery to us, nonetheless, it has been 2 years since it happened. My divorce prolong the application process which was eventually filed on 09/02/2011. Went throught the entired K-1 Fiancee visa process, including a maternal DNA test that was required for my stepdaughter. To make my story short, we completed the K-1 process on 07/15/2012, to be told at the last inteview that a I-212 Waiver was also required for violation of 212(a)(9)(A)(i). The waiver was required because my fiancee, unknownly and out of good faith, signed the paper work the custom agent gaver her. Not to mentioned, no interpreter was provided for signing. Finally, the I212 was sent 09/25/2012. Now, my questions are as follow:

Does any one know how long the process takes?

Is the application sent to the US embassy in El Salvador or in the US?

Is a I-601 required if there were on other misrepresentation/fraud/or criminal records ?

Any input is much appreciated. Thank ya'll!
