移民局的回信說：your case is currently under review.

"You should receive a decision or notice of other action within 60 days of the date of the letter". Anybody know if it is true that I will receive a notice within two months? My I-140 was approved last year in Aprl (NIW), and 485 is still pending (filed Sept 2004). Since it is already outside of processing time, I called the center and got this notice. Will I receive the approval notice in two months?
many thanks
