My I-485 already exceeded the process date at Nabraka center for 4 months. Mine receipt was in Jan, 2002. Their current process date is May 31, 2002.
I asked the status and received letter in early Oct. from USICS said that my I-485 is pending for security check. I asked again Nov. (after 30 days passed) and going to receive a letter soon. I guess must be same security check again.
Does any one experience like that at Nabarska center? How long this "security check" takes? Any help is very much appreciated.
