as i know the SIV program is close ,but the IOM program is still open and never close because its is a refugee not a migration so its still open in all countries have a war or non-established security .
every one can applied to IOM program but you should have worked with US.army or any security station in iraq or in the world .
if you not worked with any company and get threatened so you can't apply to IOM program but you can apply to UN program but you must be leave your country and go to nearest country on you its have a UN program offices and open.like jordon ,lobnan ,turkish .
the process can take a more then 1.5 to 5 years this up to your case and your threaten story.
i hope to be helpful
thank's for all
pray to our God to leave iraq as soon as possible please
regard's
