Please help, parents immigration sponsorship xw20112014-03-25 22:33:33

I submitted I-130 for my parents in Aug 2013 for immigration.

Now my mother's case has been transferred to NVC on March 7th, when can she expect the interview in Guangzhou?

My father's case is still with USCIS Texas Service Center. I have sent email, mailed letters to expedite it, but no response so far.

I really need both of them go to interview in Guangzhou together. Anything else I can do to help?

My baby will be born in Oct, I would love for them to come here and witness the new born. 

Thank you so much.

父母同时递交的移民，申请现在一个转NVC， 一个还在USCIS， 两人会不会不同时去面世，怎么办啊。
