Egypt's President Anwar Sadat, the first Arab leader to accept President Carter's invitation for face-to-face talks on the Mideast, will make a "working visit" to Washington April 4 and 5, it was announced yesterday.

Carter already has met Israel Prime Minister Yitzhak Rabin, and invitations have been extended to other Middle East leaders in an effort to bring peace to that troubled area.

The White House said Sadat and Carter will discuss "in depth continuing efforts to move toward peace in the Middle east, as well as other matters of mutual interest in our bilateral relations."

Carter will meet with Syrian Presiden Hafez Assad in May when he goes to London for an economic summit for industrial nations and a North Atlantic Treaty Organization conference.

Carter told 30 newspaper editors, publishers and broadcast officials at the White House yesterday there are strong indications that today's Arab leaders want to make peace more then their predecessors did.

"We see potential progress in 1977 and are uniquely hopeful" about the Middle East, he said. "I believe our country is willing to devote a great deal of attention" to peace efforts.

On another subject, White House press secretary Jody Powell again said Carter has no plans to include wage-price controls in the "very strong" anti-inflation package he intends to announce within a few weeks. Powell said part of the anti-inflation program would be directed at greater consultation among government, business and labor.

Carter also received a letter from 57 senators praising his effort in the area of human rights. Powell said the letter shows "the world we speak with one voice" on the subject.

Meanwhile, the White House announced the following nominations:

Robert H. Meyer, a California cattleman, to be an assistant secretary of agriculture for marketing services.

James F. Leonard Jr., president of the United Nations Association, to be the deputy representative to the liner-national organization.

Msgr. Geno C. Baroni, president of the National Center for Urban Ethnic Affairs here, to be assistant secretary for neighborhood and consumer affairs in the Department of Housing and Urban Development.

Chester C. McGuire Jr., a planning consultant and assistant professor at the University of California at Berkeley, to be assistant HUD secretary for fair housing and equal opportunity.

At the close of the business day, Carter and his family flew by helicopter to the presidential retreat at Camp David, Md., for the weekend.He and Mrs. Carter were accompanied by Amy, 9, sons Chip and Jeff and their wives, and Chip's infant son.

The President and First Lady strolled hand in hand from the helicopter to their lodge at the Catoctin Mountain campsite.
