For other Ukraine families who might be interested: this isn't exactly news, but it is straight from the (Zaporozhya) horse's mouth. Even though our registration doesn't run out until March, Will went to our nice, helpful, professional, regional OVIR to ask about the new law that went into effect on September 10. (If you don't think all those words should be used in one sentence, come to Zaporozhya! I am not being sarcastic.) We thought they had probably had enough time to figure it out by now. And... they said the new law is being amended on December 25. So, come back at the end of January to see how it has worked out. Maybe that's not exactly news, but I hadn't heard about any amendments before that.
So, everyone can be praying that the amendments will be good, but we still don't know anything.
At least, that's how it is in Zaporozhya oblast.
