Representatives of Mariel Cuban refugees facing deportation emerged from a meeting with top Justice Department officials yesterday expressing hope that the department will agree to changes in its newly announced process to review the refugees' eligibility to remain in this country.

Auxiliary Bishop Agustin A. Roman of Miami and others representing the 7,600 Cuban detainees met with Justice and State Department officials in what Roman described as "two beautiful meetings."

Raphael Penalver, Roman's lawyer, said Deputy Attorney General Arnold I. Burns "left the door open" for "modifications" in the plans.

The new plans were formulated after Cubans rioted at federal facilities in Oakdale, La., and Atlanta. The inmates were protesting a revived pact under which more than 2,500 Cubans who arrived in the 1980 Mariel boatlifts could be deported immediately. As many as 7,600 Cubans eventually could be deported.

Roman was instrumental in persuading the inmates to end their uprisings and accept the department's promise that each inmate's immigration status would be reviewed.

Penalver said the representatives gave Burns and other Justice Department officials a list of proposed changes in the review process, including giving the Cubans the right to hearings at which they could present and cross-examine witnesses. Under the current process, the review panels generally would consider only the inmate's record.

Most of the Cubans facing deportation are being held in federal facilities after completing sentences for crimes committed after their arrival.

The tone of the comments after today's meetings contrasted with more critical remarks by the Cubans' representives when Burns unveiled the review plans last week.

"It's no secret that we've not been fully satisfied," Gary Leshaw, an Atlanta lawyer who has represented the Cubans, said today. Of the request for hearings, he said, "The Justice Department people today did say that they were willing to listen to more discussion on that."

However, he noted, "for the last seven years these people haven't been treated appropriately. And you have to expect there's going to be some skepticism."

Justice Department officials "said that {full-scale hearings} specifically" would be taken under consideration, Miami lawyer Robert Boyer said.

Boyer said Attorney General Edwin Meese III appeared at the 1 1/2-hour afternoon meeting and "gave us extra confidence that these matters and these suggested changes would be highly considered."
