What is the ruling on working in a factory that produces yeast used in the alcoholic beverage industry, given the absence of an alternative and the fear of losing residency and citizenship?

It is impermissible to work in the manufacturing or packaging of intoxicants, or to assist in it in any way. An exception is made for genuine necessity that permits committing what is unlawful, such as the absence of any other work to cover the essential needs of a person and those they support. In such a case, the unlawful portion of their salary should be removed once their necessities are met by the remainder.
