The consular officer that my husband interviewed with was very nice. Only one problem, they gave him a paper that said he only needed the I-601 waiver, when he actually needed two waivers, the I-601 AND the I-212.
Side note about las clinicas:
Don't go to the one on the corner! They are theives! They charged my husband for vaccinations he already had and we ended up paying $360.00 for the medical exam instead of $190.00!!!! And they don't let anyone inside for the exam except the patient. So, I couldn't be there to speak up! VERY FRUSTRATED!!!
