Soro agreed a four-and-a-half-year deal with Neil Lennon’s side after completing a medical last week.
The 21-year-old waited for visa paperwork to be finalised before officially sealing his move to Parkhead.
Soro, who will begin training with Lennon’s squad on Tuesday, told Celtic’s website: “People talk about what you want from a team. I know Celtic will give me everything I want.
“I am joining a massive club, one of the world’s truly great football clubs with fantastic players, a beautiful history and the best fans around.
“I won’t look ahead too much but I have signed a long term four-and-a-half-year contract and across all these years I want to be part of more and more success at the club.
“I’m going to give absolutely everything to continue the success here at Celtic. I’ll give everything and more to continue the success this club has achieved.”
Soro began his career with FC Saxan in Moldova before joining Belarusian side FC Gomel in 2017 and subsequently making the switch to Tel Aviv-based Bnei Yehuda the following year.
