"This is utterly baseless. I will join my co-stars Siddharth and Divyendu Sharma. I wish I could be there for the whole period of the film's promotion," said Ali, who is likely to be in Mumbai before the film hits screens Friday.
Zafar, who worked for couple of Bollywood films including popular satricial film "Tere Bin Laden" said he was busy shooting E. Niwas' "Aman Ki Asha", a film on India-Pakistan amity.
Speaking up for Ali, a source from Viacom 18, the producers of Chashme Buddoor, said that they are "embarrassed" to read that he is not here to promote the film due to visa problems.
"Ali has never had any problems coming to India. He has been with us as much as he can. And he joins us again in a couple of days."
Earlier, several Pakistani singers and actors were denied visa by Indian government.
In June 2012, several Pakistani singers who sang songs for film "Cocktail" were denied visa to travel to India.
"The producer thought it is very unfair to these Pakistani singers, if they weren't given their due in front of the Indian media. So they decided to entirely do away with the music launch," a source close to the film's producer Dinesh Vijan said.
