You (your wife in her country of residence)will get all that specific info in the mail from the embassy in your country.Just a passport,affidivit of support , a medical report etc.
I estimate that you will receive the approval notification in about a couple of weeks(k3 from chicago) atmost as they were processing 04/28/2003 as of on 05/29/2003 the day my congressman checked on k3 visa processing date.Please let us know as soon as you are approved as you are far ahead than all of us for a k3 in thsi forum
thanks
