Phoenix FO letter receipt time to interview date

[Anony mouse]

Hi,

I am requesting people's recent experiences at Phoenix FO for N-400 interview.

Application: Jan 2017
Biometrics: Feb 21, 2017
Status: Waiting for an interview appointment letter

1. Approximately how much notice / time duration does Phoenix FO give between the interview appointment letter and the interview date?

2. Phoenix FO is currently processing Aug 2016 applications. When should we expect the interview appointment letter. Has anyone received it recently? What was your application date?

3. I remember seeing they were processing Nov 2016 and now the website is showing Aug 2016. Did Phoenix FO indeed move the date back?

Thanks,
