premise: As the record shows, it is not uncommon for H-2A workers to contact legal services for the first time as they board the bus on the way home, and an interpretation that LSC representation is available only while the alien is physically present creates the prospect that Congress authorized legal services attorneys to represent such H-2A workers only during the bus ride to the border.
hypothesis: H-2A employees are often unaware of their rights and not given opportunities to contact lawyers.
