Polish American leaders, in a meeting yesterday with President Reagan, urged the administration to double immigration quotas for Eastern European refugees. The administration last Thursday recommended raising Eastern Europe's celing to 7,000 from the present 4,500 with a corresponding decrease in the allowable number of refugees from Southeast Asia.

Meanwhile, a majority of the Senate sent a telegram to Reagan urging swift adoption of the strong immigration control policy covering both legal and illegal immigrants. The telegram, signed by 51 senators including Majority Leader Howard H. Baker Jr. of Tennessee and Minority Leader Robert C. Byrd of West Virginia, said that "uncontrolled legal immigration is creating additional burdens for the American people and is kindling a growing resentment which treatens our historic generosity toward immigrants."

Reagan met separately yesterday with delegations of Polish Americans and Italian Americans, seeking support for his tax-cut plan, but other subjects, especially immigration, seemed more important to his guests. Later, the president conferred with his Cabinet on recommendations for a soon-to-be-announced immigration policy.

Larry Speakes, White House deputy press secretary, said there was "no final presidential decision on any aspect of immigration policy.

In the meeting with Reagan, Aloysius Mazewski, president of the Polish American Congress and the Polish National Alliance, told the president that his groups' biggest concern is the number of Polish refugees in Vienna, Austria.

"All the camps are filled," Mazewski said. "Asutria is complaining."

Poles make up 80 percent of the Eastern European refugees seeking admittance to the United States, Mazewski said.

The Senate immigration subcommittee went on the record yesterday as favoring the administration's proposal to increase the number of immigrants from Eastern Europe, recommending that the full Judiciary Committee endorse the request. The House Judiciary Committee has already concurred.
