The wait time is short between document completion to interview (ours was less than 1 week).
The email response is fast (usually you get answers within 1-2 days).
The denial rate for non immigrant visa is high, but not as high for immigrant. Everyone having immigrant interview on same day with wife were granted their visa (she think)
