請教大家,婚姻綠卡485麵試,結束時遞給一張NOTE:

NOTE 的內容:

Please inquire after 180 days:

An additonal review of yr case is required to determine yr eligibility. No additional information is required from you at this time.

還說: I will review yr case and make the decision before the end of the week. Maybe I will call you.

請問有經驗的各位, 這看上去有多少被批準的可能?
要等多久?
今天沒被要求補材料或再麵試, 那將來還有可能被要求做這些嗎?
