Parent traveling on I-131 while I-485 is in process

[hameshatumkochaha]

Hi,

We applied for my father's family-based green card (I-130 + I-485 AOS) in Oct 2017. His I-131 is approved. I-485 application has gone from MSC to Phoenix, AZ (Phoenix FO). We have it ready, but did not submit his I-693 packet; so we received a courtesy notification from USCIS stating that I-693 will need to be produced if there is an interview or otherwise following an RFE. 

1. If he travels out of country based on I-131 and if he gets an RFE while he is out of country, will he be able to enter the US using his granted I-131? I want to ensure that RFE doesn't invalidate an approved I-131. 

2. What are disadvantages/risks involved with traveling on I-131 while I485 is in process?

3. Anybody from Phoenix FO applied/received green cards for their parents recently? What was your timeline?

Thanks!

1. It will not and it does not.

2. Risk of rejection which in a family based case is zero.

3. Sorry.
