Somewhat surprised that there's nothing much showing up (yet?) on VJ about the recently introduced "Uniting for Ukraine" (U4U) program.
Link to DHS page: :https://www.dhs.gov/ukraine
Link to the USCIS page for online filing of I-134 Declaration of Support : https://www.uscis.gov/i-134 (N.B. - this MUST be filed online for U4U they are not accepting paper submissions)
There is a Facebook group Helping Ukrainian refugees in the USA which is very active (at least as of now - May 2022) for people discussing U4U program.
On that group there are:
Ukrainians who have fled their country who are seeking sponsorship from Americans under the U4U program
Americans who want to find deserving Ukrainians they can sponsor
A lot of people with a lot of questions and confusion about the process. And it's fair to say the process is confusing (as all US immigration processes are). Sponsors don't know what they need to file, Ukrainians don't know what they need to provide, lots of confusion going on
I, having completed a K1 petition for my fiancee (now long married wife) 12 years ago with the assistance of VJ, thought I might point people in that Facebook group to an appropriate spot here where there might be some guides and information to assist. However seems like there's not much here.
I did find my prior K1 experience helpful when I completed four I-134s to sponsor a family of 4 Ukrainians, and I'm giving some informal advice on the FB group to others doing the same.
I'm also amazed as to how quickly the process seems to be going. For those of us accustomed to the glacial pace of USCIS adjudications, my jaw literally dropped when I submitted the online I-134s on Wed and they were approved on Fri! TWO DAYS. We're not done yet of course, next step is they contact the Ukrainian family via email to upload their documents and vaccination records. But we're very excited at the prospect the family may be here with us in the USA in time to celebrate the 4th of July.
