While filing i485 under F2A category on the form part 2 application type I am applying for an adjustment to permanent resident status because, what would be the answer ( a or b)

 it is A if u have an approved i-130 or are filing together with it

No I don't have approved i130, I am filing concurrently since f2a is current. I guess the option is 'h' other. Please provide some input who have filed in f2a category.

 You can either choose option A or H. 

No I don't think so because I chose Option a. And got a RFE saying that I need to prove that my wife is a citizen

 @budhobalak- when did u get RFE and when did you file the application? I guess you can call USCIS and let them know that you are eligible to file I-485 and I-130 concurrently as per the visa bulletin of August 2013.

Best of Luck

I got RFE yesterday and I filed it on August 1st. Don't you think USCIS people know I am filing concurrently because f2A is current. I have clearly written on I485 cover letter that I am a spouse of a permanent residence. Any one came across the situation please share ur inputs

@budhobalak, I have an RFE on the way too. It will probably get here today or tomorrow. But, I think it might be the same situation as yours. I also chose option "a" on the form and filed 130 & 485 concurrently. I will post on here once I get the letter.

Damn! I have chose the same option.So, i might get RFE too. Now, i have my finger crossed.you can call USCIS and let them know about it.

And have u guys done fingerprint yet or not? I haven't done mine yet..

@dilligaf- How did you know you are getting RFE? Did the status change on your case stating that they have sent RFE to you?

Uscis changed my i485 status to request for evidence on August 23 , and I got in mail on August 28, The RFE states that " submit evidence to establish that the petitioner on form I-130 or descendent on form i360 is a United States citizen"

Did you got your finger print notice budhobalak?

I have my fingerprint today afternoon,

 Looks like we are on the same boat. Might get mailed RFE today or tomorrow. Finger print for my spouse is scheduled for Sept. 3. Guys lets keep things updated. 

Just curious.
Is getting the notification for fingerprint is an indicator of approval of form i-130?
If not, how long does it take for i-130 to get approved for those who filed after this Aug 1?

This https://egov.uscis.gov/cris/processingTimesDisplay.do says that processing time is more than a year in both (CA and VT) SCs for 1-130 approval. Does that mean whatever blah blah notice you get now, it will take more than a year for you to kiss green ass? oops card.

The biometrics appointment was today. I found out about the RFE after checking the status of my application online. I am worried about it too. They must know that it  is concurrent filing because of the "current" status on F2A category right? Even if they didn't already know it, it was indicated in the application itself. So why the RFE? I have no idea what to make of this. Probably need professional opinion. @budhobalak, How are you going about this?

Choose option H and print spouse of a permanent residence (f2a). Add a continuation sheet with i485 and justify . That should work

REF notice has been issued on 26 August 2013 on my case as well. I had checked for option A. 
I must also have got REF to prove petitioner as US Citizen. Concurrent filing petitioners for I-130 and I-485 have similar issue in trackitt.com.
How are you guys planning to response to REF?

Will the biometrics appointment date be affected due to REF issued? 
Please share your experiences.

 I might get RFE soon too. I have been checking my wife case status and might see RFE soon. I hope I won't see it. Just in case if we get RFE,people who had replied to RFE. Can you please provide details, how you responded to RFE? 

And, Can one change the status from F1? after getting NOA1 for I-130 and I-485. 

PS: My wife is graduating this december.
