请教大家,婚姻绿卡485面试,结束时递给一张NOTE:

NOTE 的内容:

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.

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

请问有经验的各位, 这看上去有多少被批准的可能?
要等多久?
今天没被要求补材料或再面试, 那将来还有可能被要求做这些吗?
