I-485 approved and stamped

My I-485 was approved a week ago, and just took 2 minutes to get my passport stamped at Baltimore office this morning. tehy just asked me for passport, 2 photoes, and all I-94s, that's all, unexpectedly fast!!!
However, my I-140 is still pending, no any update at all.

Good luck to all on the same boat!!! Happy New Year!!!
