Oct. 1 (UPI) — Former President Jimmy Carter celebrated his 98th birthday on Saturday, with the Carter Library planning a naturalization ceremony.

The Carter Library & Museum in Atlanta plans to hold a naturalization ceremony for 98 people becoming American citizens. The Carter Center has also invited people to submit birthday wishes and photos.

“As the longest-living president in U.S. history, President Jimmy Carter has had a remarkable life of service that deserves worldwide celebration,” Carter Center CEO Paige Alexander said earlier this week. “Whether here in Georgia or in hard-to-reach regions around the world, millions of people have benefited from President Carter’s commitment to making the world a better place.”

Other former Presidents wished Carter a happy birthday and commended his public service.

Former President Barack Obama tweeted, “Happy 98th birthday, President Carter! Your dedication to public service and the work you and the @CarterCenter have done to lift up others is an example we should all follow.”
