Answer:
The answer is that the ratio is likely the same.
Step-by-step explanation:
There is no equivalent of how many unskilled worker can replace a skilled worker. Also, it's a fixed ratio of one skilled worker and two unskilled workers to produce a unit of output. Therefore, even though the wage of unskilled workers decreases because of a surplus in immigration of unskilled workers, and assume that the rest is the same, firms won't hire more unskilled workers.
