The Carter administration will send Congress its plan for reorganization of the U.S. Information Agency within 60 to 90 days.

President Carter's nominee to head the USIA, John E. Reinhardt, told the Senate Foreign Relations Committee yesterday that the administration does not yet have a position on whether the Voice of American should remain part of USIA or become independent.

Reinhardt said he personally favors keeping all U.S. information programs under centralized control.

Sen. Charles H. Percy (R-III.) and other senators favoring an independent VOA don't intend to wait for the administration's reorganization plan, a Senate source said.

Percy plans to introduce a measure that would establish VOA under a presidentially appointed and Senate-confirmed board when the Senate considers the USIA authorization in about 30 days.

Percy told Reinhardt that their disagreement over VOA would not prevent him from voting to confirm Reinhardt.

Other members of the committee praised the 57-year-old career USIA officer effusively, indicating that his confirmation is assured.

A second Carter nominee, Richard C. Holbrooke, 35, met a similarly friendly reception. If confirmed, he will be assistant secretary of state for East Asian and Pacific affairs.

Holbrooke told the committee that Carter "is deeply interested" in moving toward normalization of relations between the United States and Vietnam.

The President hopes that the commission led by United Auto Workers President Leonard Woodcock, which arrives in Hanoi today, will resolve the question of missing American servicemen in such a way that relations between the two former battlefield foes can improve significantly.

Holbrooke was not asked whether relations can improve in the absence of U.S. aid to Vietnam or whether the administration believes Congress can be convinced to lift the legal ban it has imposed on providing Hanoi with any aid.

The administration has not yet begun "a formal, intensive review" of the problems of normalizing relations with China, Holbrooke said.

He said the United States has a considerable interest in the peaceful resolution by the Chinese on Taiwan and in Peking of their disputes. Both of them agree there is only one China, but each claims to be it.

Holbrooke also told the committee that the United States will consult closely with Japan.
