Qs on B-2 visa for my parents

Hi, everyone,

I'm trying to get everything ready to invite my parents to visit us. My hu*****and (F-1) and I (F-2) are currently on I-485 pending status (I-140 approved). I have two questions:

1. On our invitation letter, do we have to reveal our I -485 pending status or just say F-1 and F-2 status?
2. On I-156 form, there is one item asking what kind of status of the invitors ( my hu*****and and I)are. Again, do we just say F-1 and F-2 or I-485 pending?

Have been this forum before and learned somebody suggested just say F-1/F-2, no need to add I-485 pending, but if somebody has the same experience, I'd appreciate your inputs very much!!
