Yesterday I checked my I-485 status USCIS website, and it was marked decision. (It has been marked as decision since 15 days ago. I stated that the review has been completed and the decision will be mailed.) Today I tried to check my status (and my family status), they are all gone. Does that mean that my I-485 has been approved???IT APPEARS: At this time USCIS cannot provide you with information for your case. Please contact the NSCS 1 (800) 375-5283 for additional information. To view the status of a case, please enter the corresponding application receipt number. The 13-character application receipt number can be found on application notices you have received from the USCIS. It begins with three letters such as (EAC, WAC, LIN, or SRC). Dashes ("-") should be omitted when entering a receipt number. However, all other characters, including asterisks ("*"), can be included if listed on your notice as part of the receipt number.
