Notice of K3 application being transferred to Missouri 18 October, 2005
We went the K-3 with my wife. During the wait for an interview she became pregnant and barely beat her giving birth by 3 months. Unless your wife gives birth no adjustment, or paperwork, should be needed.
Back in 2006 when going through this mess I contacted my local US representative and got they're help in moving things forward. At times a politician can seem useless until they might need your vote.
