The controversial 'Cafe' corner at Interlagos will still be in place for the 2011 season finale in November.
Following two recent fatalities in stock car races at the fast left-hand kink, the Sao Paulo circuit has agreed to make changes that will require significant work including the removal of a grandstand.
The FIA's Charlie Whiting inspected the section at the weekend, according to the Agencia Estado news agency.
It was reported afterwards that work on the revised section will take place in the first six months of 2012, in time for next year's F1 race.
"Charlie liked what he saw and it's now a matter for the engineers," an official is quoted as saying.
"It will take time, and the timetable that we have begins only after the (2011) Formula One (race)," he added.
