US Immigration from Philippines

Hello, I have a big question and not sure it can even be answered here? I have a filipina girlfriend for 2 years now and have been there for month long visits 3 times now... the last trip we decided to get married... I came back to the u.s. and started to gather the documents needed... I had all but forgotten my criminal history... I got my FBI file and my state history.. I looked through it and realized I was in trouble with the process...I had a bad spell in my life 25 years ago... 3 dui.... no felony and a domestic and simple assault... I know it sounds bad but I didn't hurt anyone.. but yes under the letter of the law I was guilty... I slapped a guy in my early 20s and during an argument I grabbed my wife..

My question is... do I have any hope of approval for the k-1 to bring my fiance from the Philippines to the u.s.?

I am not the same person I once was and have had a good productive life since... 20 years at the same job.. I own a home... it's the only issue I have.... my past.

Filed for the AoS earlier this year w/ the EAD, but opted to not file for the AP because my wife and I decided that we didn't anticipate needing to travel for the next year, therefore it would be best to save the money than spend it for AP.

Well my work decided to schedule a work trip to Mexico in September and my wife really wants to go, which based on AoS time estimates I don't think is possible, therefore I was thinking it may be worthwhile to file the AP today, but unsure how common it is for AP to be approved within 3 months of filing date. I know every case is 'different', so no definite way of knowing, but really just wanting to know if it's very common, common, uncommon, rare, or very rare.

Key Dates:

• AoS Filed: March 24
• Biometrics: Apr 21
• EAD Received: May 8
• SSA Appt: June 5
• AoS Appt: PENDING

We received receipts for everyone like this today. Cards have not been received yet, They will not mail them to PI will they? Or are they for the visas mailed in October, but why are we just getting the receipts now?

Please see the attached receipt for your payment of the delivery fee. This is for the US visa/docs delivered by LBC.
This e-receipt is for your reference only.

My fiance is missing the Certified duplicate of the I-129F form. How do we request a copy, and how long does it take to send it?

Can they send it via email?

Still feels slightly surreal that my visa got approved and we're like, now what?

So my questions are:

1. When would I likely receive (via LBC) the passport and sealed packet in terms of working days after the interview?

2. Can I make an appointment for CFO now even if I don't have my passport yet?

3. Say I have my passport with the visa, is it easy to set an appointment for CFO? I mean when choosing a date like the next day?

It would be a bummer if the available slot is next week similar to that of NBI Clearance appointment.

Thanks for the responses!
