J+A

hey Joe Kwa,
if you take a look at my profile and status updates you can have some sort of idea how long our case took.
Our case was completed on June 19 and on June 27 (called NVC and DoS daily) my wife's interview was set for August 28 at Bogotá.
We were so happy that we got through the NVC phase in only 20 days but then disappointed that the interview was set 2 months later but as of today 11 days to go!!!
Good luck!

Hey Carlos. I am filing for my wife in Colombia also so I can help you out with my personal experience. This doesn't mean we will have the same exact results but it helps to have estimates in my opinion.
1. Can I e-mail the DS-3032 choice of agent after there is a case number or again wait for instructions by mail? Can this be done by email for all instructions to be sent to you?
After you call NVC and they give you your new case# BGT2012XXXXXX also ask for the Invoice Identification Number. This "IIN" will be used to log into the Department of State payment portal website to pay your fees here https://ceac.state.gov/CTRAC/Invoice/signon.aspx
The same day you receive your NVC case# your wife (beneficiary) should e-mail the template found here http://www.visajourney.com/wiki/index.php/Email_DS-3032_form to NVCInquiry@state.gov
She should receive an automated-generated e-mail indicating they have received it, this will take some days for it to clear until they check her e-mail message and tie it to the case in their system. When you log into the the DoS payment portal and see IV fee invoiced that means they have accepted her DS-3032 and u can pay the IV fee and send off the IV packet.
2. Do you wait for the AOS bill to come in the mail or I can simply pay it online?
After my case# was given the AOS bill (@ DoS payment portal website) was invoiced the following week (4 days later) then I paid it. It's best u login daily to see when it's invoiced. (You may see error messages that is normal).
If you wait for them to notify you it will prolong this process tremendously.
3. Once the AOS shows PAID online do I send the I-864 packet or again do I wait for instructions by mail? The same thing with the DS-230 fee and packet?
Yes, once the DoS payment portal shows PAID mail your packet. At this website you will be able to print the Cover Sheet that is mandatory to be the first page for your Affidavit of Support (AoS) packet.
4. If you don't receive anything do you simply call them to find out what is happening?
After you send your AoS packet you want to start calling NVC to find out if they accepted it, the same goes with the IV (Immigration application) packet, and then again to find out the interview date once your case is complete at NVC.
Currently, we are waiting for my wife's interview date, August 28 @ 8:30AM
You can check my profile Timeline and my Status Updates to see the flow of how I did things and contact me for any questions.
Wishing you and your wife a quick VisaJourney
Good luck!

Hey Mike!
I see we have similar dates. Our case completed @ NVC on June 19 but my wife's interview is until August 28.
I see your case completed on June 22 and interview is set for August 16, nice!
The letter you attached from NVC is exactly identical to ours.
My wife is still planning to take those items marked as O - Original because you never know what they might ask for and not having it means another trip to the Embassy.
They are also listed at the Bogota US Embassy's website http://photos.state.gov/libraries/colombia/231771/PDFs/IVPkt3-4Instforinterviewmedicalexam_Mar%2012_.pdf
My wife did have some trouble registering at this website http://colombia.usvisa-info.com as indicated on the above link.
I hope it's correct.
Good luck to you and your wife, can't wait to see approved in your profile!!!
