The 22-year-old Brazilian is already an occasional Friday practice and reserve driver with the Tony Fernandes-led team.
And according to Agencia Gazeta Press, he is working hard to find the money to replace either Jarno Trulli or Heikki Kovalainen for his home event at Interlagos late next month.
"For months I've been talking with sponsors to get the support needed to compete in this race," said Razia, who in 2011 raced for Fernandes' GP2 team.
Previously, the biggest hope was that he will get the green light to practice on Friday ahead of the 2011 season finale.
"For Brazil, it is much more interesting to have a driver on the grid, representing new blood," he now insists.
"The country is in a period of great economic growth and it would be interesting for companies to have their names linked to an event of first-class technology and global exposure," added Razia.
