How long does it take to get the verification of non-filing?

I sent 4506t form to them. It was there on March 16, 2017. It’s been almost 3 weeks, but I haven’t got anything yet. Does anybody know how long it usually takes? Are there other ways to get it faster?
P.S. I live in Reno NV

You can get it from an IRS office. Wait times will depend on the office.

@twoinanddone what did you mean by get it from the IRS office? you meant going up to the IRS office and asking for one?

Yes, walking into an office and delivering the form. They should be able to process it while you wait. It is April, and they are busy.

@twoinanddone Oh thank you so much

@twoinanddone Do I need to make an appointment before?

@PThananun

Yes, you must make an appointment.

@Meganerd2012 Thank you
