我該不該遞４８５？

NIW 140 approved. Eb1b 140/485 concurrently filed. Eb1b 140 approved but 485 is till pending.

But being afraid to
[1] lose the permenant job which is required by Eb1b.
[2] NIW visa number goes back.
[3] miss the opportunity to pay much less money.

The lawyer said multiple pending 485 could cause confusion and then delay. Is he right?
