Abramovich flew into Israel early yesterday in his private jet, and received an Israeli identity card under the Law of Return, which allows Jewish people to become citizens of Israel.
They added: "His documents were examined under the "law of return" and he was indeed entitled to immigrant status in Israel, and as a result he was issued an immigration visa". He recently was denied a new visa for the country.
Once Abramovich completed the immigration process, he instantly became the richest person in Israel-with a worth of more than $13.5 billion.
The incident led to cooling relations between London and Moscow, and led to dozens of diplomats being expelled from a number of countries. Amid increased scrutiny and a tightening of visa regulations, Abramovich, who had attended almost every Chelsea game since 2003, missed Chelsea's Football Association Cup final win against Manchester United earlier in May. He has owned the team since 2003 and was present at almost every game until his visa problems began.
Chelsea FC owner's previous tier-1 visa was granted before regulations were tightened.
From 2000 to 2008, Roman Abramovich served as governor of Russia's far-eastern Chukotka peninsular and injected millions of dollars in investments to the distant region.
Carrying one of his children, Russian Jewish billionaire Roman Abramovich arrives at the Beresheet Hotel in Mitzpe Ramon in southern Israel on April 14, 2014. "Much of the work we do has been made possible thanks to Mr. Abramovich, and we are deeply thankful for his continues support".
