Armstrong is a seven-time Tour de France champion
Lance Armstrong's Astana team have given financial guarantees to cycling's governing body paving the way for their Tour de France participation in July.
The International Cycling Union (ICU) had threatened to withdraw Astana's Pro-Tour licence if the team had not met the UCI's financial requirements.
Astana receives most of its financial support from Kazakh state holding company Samruk-Kazyna.
But the Astana team's riders went unpaid for two months.
Armstrong, who is considering buying the team, was joined by all but one of his team-mates in blanking out the sponsors' names on their shirts from the seventh stage of the Giro d'Italia in protest at the team's financial problems.
The Tour de France starts on 4 July, when Armstrong will attempt to win the race for an eighth time.
