I doubt it. There's a reason why employers have American employees fill out the Department of Labour self-identification survey during the hiring process. If the government sees that nine Asian, six white, three black, and two Hispanic individuals apply for a position, and the company chooses to only hire eight of the Asian applicants, that would definitely raise red flags. Especially when the racial demographics of the company disproportionately represent Asian individuals. Its pretty easy to see what the company is doing in that case.

Further, the Supreme Court has ruled that it is not discrimination to hire on the basis of race if it affects the persons performance with the job. For example that's why movie studios aren't hit with discrimination lawsuits for rejecting black individuals when casting for Abraham Lincoln. But there is no way that a court would accept that a technician or engineer position is in any way affected by a person's race.

Further, there is no legal argument that an engineer knowing mandarin in any way effects their performance, when a company worth billions of dollars avoid English translations of documents for their US based plants, with the sole intention to creating a discriminatory barrier.

The company has no plausible deniability here, and any court would see right through it. White owned businesses tried many of the same tactics with black individuals, and precedents have been set because of that.
