WASHINGTON - Senators Tuesday had few questions for a Cuban exile from Miami who was a top Latin America policy advisor in the Bush administration and is now on the verge of becoming director of the U.S. Bureau of Citizenship and Immigration Services.

Emilio González, introduced to the Senate Judiciary Committee by two Florida Republicans, Sen. Mel Martinez and Rep. Ileana Ros-Lehtinen, said he would ''bring an understanding of national security and my own personal immigration experience to bear'' on the new job.

Only three senators attended the confirmation hearing for González and two other nominees: Julie Myers to head Immigration and Customs Enforcement, and James O'Gara to be deputy director of the Office of National Drug Control Policy.

González, whose family fled Cuba when he was 4, was an advisor on the National Security Council and served 26 years in the U.S. Army. He said he would concentrate on ''good customer service'' in the naturalization process and handling asylum cases, ``but we don't want to sacrifice national security to expedite things.''

Sen. Patrick Leahy, D-Vt., and the ranking member of the committee, briefly questioned González's immigration expertise and Myers' limited management experience, but also said in a prepared statement that Bush is ''owed some deference'' on his nominees.

Sen. John Cornyn, R-Texas, and chairman of the immigration subcommittee, said he expected swift confirmation of the three nominees.
