Obruc. is about 215$, so I guess is expensive. My wife sent it on Thursday, I am not sure about the form because from my understanding,notification are to be made if there was any changes.It goes this way YOUR IMMIGRANT VISA(S) APPEAR(S) READY TO BE ISSUED, IF THERE HAS BEEN NO CHANGE IN YOUR FAMILY CONFIGURATION. IF THERE HAVE BEEN ANY CHANGES, PLEASE CONTACT OUR OFFICE BEFORE PROCEEDING.
You are asked to submit your passport(s) and documentation BY COURIER within 15 days. We recommend DHL courier, using a pre-paid return envelope. Oh well, we submitted passport only because the email about family update looks generic to me. Most of the requirements are for accompany people.
