GC Extension while citizenship is in process

[Simran5]

My GC expires on Mid September and I have my Citizenship interview on August 5th. I am hoping I will have my naturalization ceremony by September but cannot be sure.

1. Do I need to renew my GC or just plan that I will have my citizenship by sep/ before the GC expires. 

2. If I don't extent my GC and I don't get my citizenship by mid sep- I am at risk of being illegal in the interim or have issues at the naturalization ceremony?

3. Is there a potential to have issues at the citizenship interview if I have applied for GC extension?

 

Thanks..Appreciate your guidance here..
