Over the objections of Secretary of State George P. Shultz, PLO Chairman Yasser Arafat is expected to visit the United States later this month to address the U.N. General Assembly.

Arab diplomats say Arafat, who along with two PLO diplomats applied Tuesday for a visa to come to the United Nations, is expected to announce formation of an independent Palestinian state on about Nov. 30 and request U.N. observer status for the new PLO government.The Israeli government and Jewish groups already have protested a visit by the Palestine Liberation Organization chief, and Shultz in a letter made public Wednesday said he did not welcome a visit by Arafat.

Shultz in a Nov. 1 letter to 51 senators who protested any visa for Arafat wrote, "Like you, I have no desire whatever to see Arafat in the United States."

The PLO, which has no diplomatic relations with the United States, is the only organization that must apply for a visa through the General Assembly.

Arafat last visited the United Nations in November 1974, when he delivered a 90-minute speech.
