US Immigration from Sri Lanka

Hello, I am a naturalized US citizen is living in a foreign country ( Sri Lanka) with wife and family. However I have a house in Houston Texas and paying mortgage on it. I filled I-130 Petition Wife. I just looked in to USCIS status and it says few days ago they have issued a letter to me requesting evidence(RFE). I think its they wanted to see my income ? if its a such a request how to respond to it ? coz Last few years I have filled 1040 with zero income.

Do i have to file amendment tax returns and show some income ? pls help. I have no idea what to do

The US Embassy in Sri Lanka rejected our I-129 one year after the interview, then rejected our I-130 2-1/2 years after the interview. Rather than appeal we have determined to reapply for I-130. The online I-130 allows the choice of an Embassy outside their country of last residence. Does this work? Say for example we chose India...

Thanks for any experience.

I have house in a foreign country worth about $150000.00. Can I use it to show my assets ?

The child   s U.S. citizen parent has been physically present in the United States for a period or periods totaling at least five years, at least two of which were after 14 years of age.

Hi, I was a green card holder and became a naturalized us citizen. I was 8 months short of 5 year physically presence in USA, So my child 4 year old CRBA was denied. I am currently not living in USA. I am with my family and children. My wife's I-130 is in processing status. So, we all are planning to come to USA. once the child has come to USA with immigrant visa I can file N-600K or I just have to wait 8 months to complete my 5 years in USA and then file N-600K?

After my interview I got 221g paper and they asked me to submit required document soon.so I did it soon. After one month later my ceac status changed to "ready" from refused. Again date updated twice but status still showing ready. What does it mean? I'm from srilanka, Colombo
