US Immigration from Philippines

Please help we are running out of time. My fiance is in the Philippines and Im here in USA. We got the approval for the I-129f and the approval expires Sept 7th in 4 days, I just got the info from NVC in Manila, Philippines for us to file for interview etc etc, Do we file for immigrant or nonimmigrant for her. Please help, I have been stressing out the whole time about this.

Our paperwork has made it to the Visa Center in Manila Thank God. We still need the interview and Medical. do we schedule the Medical our selfs and where do we schedule it at? Cebu or Manila and how.

As title says: for those DQ'd in August of any year, when was your interview date?

I just got email from NVC telling me my Fiances approved I-129F was received in Manila. But what I dont understand is on all the paper work I filled out I put her name as (Name A) J. (Name B), on the email and on the I-797 it says (Name A) O (Name C) not (Name B). But where did the O come from?? Will this cause any problems when she goes to Manila for her interview. Im not rich and can not pay for her to fly back and forth to correct these issues.

My wife is now a US citizen. She is looking to apply for her parents to come over. They have children, 1 is 36, 1 is 24, 1 is 21, 1 is 18 the last is 16. She would like to apply for her parents and her 16 year old sister at the same time. When the parents get here in 2 - 3 years, have them apply for the others once her parents get a job. I told my wife it may be possible for the 18 year old, but the others would be a wait of 8 to 10 years. Although I have read elsewhere that it's between 3 to 5. What would be a good approximate for this? Thank you.
