Orioles manager Buck Showalter said he is prepared for Aceves to be gone a week, but he's been told that the process could take just five to six days.
Since Aceves pitched in the Mexican Pacific League and late in the Caribbean Series for Mexico in the offseason, Showalter said he isn't worried that Aceves will fall behind.
Aceves played a significant role in Mexico's Caribbean Series win. He allowed just one earned run over seven innings in Mexico's semifinal win over the Dominican Republic on Feb. 6 and also tossed a quality start (seven innings, five hits, three earned runs) in a victory over Cuba five days before that.
"I think he'll be fine," Showalter said. "It may not be a bad thing at all. You can tell he's pretty crisp right now. I was in the batters' box doing a drill and he threw the ball to the plate. Hope he didn't have an Orioles-Red Sox flashback there."
South Korean right-hander Suk-min Yoon must also obtain his work visa, but is planning to obtain it by going to the United States embassy in Canada instead of making the day-long trip back to South Korea for processing.
Right-hander Liam Hendriks, who was designated for assignment by the Orioles to make 40-man roster space, was claimed off waivers by the Toronto Blue Jays.
For Hendriks, it was third times since December that he has been claimed by a different team. The Orioles claimed him off waivers on Dec. 23 from the Chicago Cubs, who claimed Hendricks from the Minnesota Twins 10 days earlier.
Hendriks was 1-3 with a 6.85 ERA in 10 games (eight starts) last season for the Twins and is 2-13 with a 6.06 ERA over his 30 big league games, including 28 starts.
Had Hendriks cleared waivers, he would have been reassigned to the Orioles' minor-league minicamp at Twin Lakes Park.
