RAWALPINDI, Pakistan, Dec. 22—Pakistan's new President, Zulfikar Ali Bhutto, today ordered the impounding of passports belonging to the nation's 22 richest families and to their relatives and dependents.

Mr. Bhutto, a wealthy landowner himself but a Socialist, said that he had ordered the impounding of the passports as well as the sealing of Pakistan's borders to all but religious pilgrims to prevent the flight of capital from this country.

He also warned that “time is running out” for those who had not heeded his announcement Monday that if Pakistani capital invested abroad was not brought home immediately harsh measures would be taken.

“The 22 Families” are known to nearly every Pakistani as the nation's economic aristocracy. They are enormously wealthy by any standard and are frequently criticized by social reformers who note that the per‐capita income in Pakistan is about $100 a year.

For the time being all Pakistanis are forbidden to leave the country, except a few thousand who are authorized to make pilgrimages, to the Moslem shrine at Mecca.

Mr. Bhutto today swore in an aging Bengali politician, Nurul Amin, as his Vice President. Mr. Nurul Amin is not likely to be given any real authority but stands as a symbol of Mr. Bhutto's determination that East Pakistan should still be considered part of the nation.

The rest of Mr. Bhutto's Cabinet was to have been sworn in today but the ceremony was postponed for several days. Actually Mr. Bhutto himself holds all the important ministries and is virtually a one-man government. He is President of the nation, Chief Martial Law Administrator, Minister of Foreign Affairs, Minister of Defense, Minister of Interior and Minister of Interprovincial Coordination.

But he said today he intended to divest himself of the title Chief Martial Law Administrator “as soon as possible.”

Since his swearing in on Monday Mr. Bhutto has been removing military control from a wide range of Pakistani institutions.

The governors of the four West Pakistani provinces, all army generals, have been replaced by civilians, one of whom is a cousin of Mr. Bhutto.

Mr. Bhutto has also made changes in the Pakistani press, removing a general who had been chairman of the powerful National Press Trust.

In other developments today a team of the International Red Cross arrived here to begin tracing prisoners of war and West Pakistani civilians now in Indian‐occupied East Pakistan.
