Question:

Generally an interview is not requested at the I-829 stage

It is a possibility BUT is also highly unlikely. USCIS very recently published a new EB-5 rule dealing with cases that have been on hold for over 10 years (13 to 16 years). THOSE folks are highly likely to be interviewed if they have not already been or even if they have they might be again.

Usually, no interview is required, although USCIS has the authority to conduct an interview within 90 days of the filing (according to the regulations).

USCIS reserves the right to refer an investor to an interview conducted by a USCIS District Office at the I-829 stage.

No interview is required at the I-829 stage.

Pursuant to 8 C.F.R. § 216.6(b)(1), USCIS has the right to interview the EB-5 investor. However, USCIS must either arrange for an interview within 90 days of the date on which the I-829 was properly filed or waive the interview requirement and adjudicate the I-829.

Ordinarily, an interview is not required on the I-829 stage.

The USCIS generally does not require personal interviews, although the authority to conduct interviews is listed in the immigration regulations.
