President Daniel Ortega of Nicaragua said Monday he would not go to the United Nations this week because the United States failed to issue enough visas for his party and imposed unacceptable restrictions on his stay.

"I cannot accept these rules because the United States cannot decide when, how and with whom a chief of state can visit an international organization like the United Nations," Ortega told a news conference.He complained that the United States should not require 15 days notice to approve the trip of a chief of state and his party to the United Nations.

Ortega said the Reagan administration refused to issue visas for half his party and also refused to issue visas for Nicaraguan journalists who wished to accompany him.

He also said the United States limited his travels to four boroughs of New York City. Ortega said this would prevent him from visiting the home of the Nicaraguan ambassador to the United Nations, who lives outside that area.

"The United States has violated international norms and its promises to the United Nations and has broken the principles of the United Nations," Ortega said.

He said that at the United Nations he had hoped to describe the extensive damage done in Nicaragua by Hurricane Joan and plead for international help.

Ortega said he also wanted to confer with U.N. Secretary-General Javier Perez de Cuellar about a new proposal for the United Nations to participate in verifying a Central American peace accord.

Ortega was in Mexico for the inauguration of President Carlos Salinas de Gortari. He said he was returning Monday to Managua.
