1. I filed I485 last month and got a letter recently scheduling me a biometrics (code3). I saw here in this forum some said 2nd FP, my question is: is 2nd FP absolutely required in the green card process or only necessary when the first expired? In other words, does everyone need a 2nd FP?
********** theoretically, only necessary when the first expired
2. What's the procedure for I485 in general? After FP, what's next? NC?
******** NC
3. About NC, what's the determining factor on the speed of it? The sensitivity of your area/field or the complexity of your past (e.g., moved a lot, changed jobs a lot), beside individual variation/luck?
****** many potential factors. but the major one, I think, is that FBI does not do their work in a timely manner. If your NC is pending for more than one year, then you mgiht need to take an action to file WOM. Send FBI FOIA request first to see if they have any records about you in their central system. If no, it will be an good excuse to take an action after you consume up all adminstrative means.
