The Prime Minister has accepted an invitation to come to Discovery Park in Sandwich.
South Thanet MP Craig Mackinlay, who is at the centre of an election scandal, asked the PM to visit during Prime Minister's Questions in the House of Commons on Wednesday.
Mr Mackinlay, who is in the midst of allegations about election expenses, said: "It's been five years since the announcement at Pfizer to scale down operations, since then with enterprise status there has been a true renaissance of employers on site with employment level now up to its previous position."
He said he has previously invited David Cameron and would like to invite him again to visit the Sandwich site.
Mr Cameron said: "I am delighted to answer that offer. I would like to go. I remember very well, it was early in the 2010 parliament that Pfizer made that decision and there were real concerns it would lead to an exit of jobs and investment."
Mr Cameron praised the science minister at that time, David Willetts, for encouraging businesses to locate to Mr Mackinlay's constituency and help make it what it is today.
Discovery Park is a science and business zone in Ramsgate Road, with a number of innovative businesses that have located from all over the world.
