Final Processing Letter - tax return, recent income/employment, employment letter

[watermelonson 0]

My interview was June 14 in Guangzhou, China. At the end of the interview, I was given a green "Final Processing Letter" paper. My petitioner(my dad), is self-employed, so does he write a letter himself saying he's self-employed? He also has a business license, should I include that? The license expires June 30, 2017, and he already paid the renewal fee, but the actual new license comes in 3 weeks. Should I include the renewal statement?  

 

Besides providing recent paystub, should I also provide bank statements showing the money has gotten transferred to the bank account? Not sure if I should do that because the statement shows withdrawals of money as well...

 

They already saw his 2016 tax returns and saw his recent income evidence in the interview... don't understand why they want to see basically the same thing again... His 2016 tax return is above the 125% poverty line, but 2015 tax is not, it's $300 under. Is 2015 tax return gonna be a big problem  T_T

 

 

 

Was anyone else in a similar situation? Any replies would help! Sorry for asking SO many questions. Thank you guys in advance!!
