The CONCACAF football body is backing FIFA's proposal to restrict future presidents to eight years in office, and 12 years for executive committee members.
CONCACAF, which governs football in North and Central America and the Caribbean, says it fully endorses a 10-point plan suggested by a FIFA working group on anti-corruption reforms which meets Tuesday in Zurich.
UEFA is opposed to the plan, and wants a 12-year limit on the FIFA presidency and no term limits on FIFA board members.
FIFA's suggested plan falls short of wider-ranging proposals requested by its advisory group led by Swiss law professor Mark Pieth.
CONCACAF includes 40 football countries, though just 35 are full FIFA members with voting rights. The reform slate will be decided at the FIFA congress in Mauritius on May 31.
