Principal 和derivative child都是CLASS IB1, 在erivative child 的I-485表, 是否要填Priority Date?
-No, but need to provide the copy of the principal applicant's I-485 receipt notice and the relationship proof between the two.
在I-360的批準通知, Priority Date和Receipt Date 是一樣的. 但是CLASS IB1不是不用Priority Date嗎?
-The copy of I-360 approval notice is needed which tells the qualification for I-485 filing.
