The 23-year-old is currently on a season-long loan from ENPPI, but the Black Cats have an option to make the deal permanent at the end of the season.
Arsenal and Manchester United are reportedly among the clubs being linked with a move for the winger, who has impressed for Sunderland.
“I like the vibe here,” Elmohamady said.
“It’s a nice place and people are so friendly. Everyone has been so helpful, especially here at the club. I feel as if I’m back home in Egypt.
“I want to keep on playing in the Premier League, not for a year or two only. I want to do well for myself and my country.
“The gaffer is a very good manager, and he’s so respectful. He likes commitment. He trusts his players and we should repay his trust.”
