He cannot cross the border to come up to seek work by his own act. When he is brought up. it is for definite needed work to be performed within a reasonably ascertainable time. The domestic worker on the other hand may be a resident of the area of employment. a student. or a migrant worker who moves with the crop. He may be alone or with his family. He needs no entry permit and is not required to leave the country.
