US Immigration from Lithuania

Hi Members,

I have my Naturalization Oath Ceremony in a few weeks. Therefore, I will soon have my US Passport.
Here are my questions:

• My mother is coming to visit for Christmas for a month and is thinking of staying to live in US
  • She has her flights booked and her ESTA ready
  • Should I wait to apply for her green card until she is here? This way, would she qualify for adjustment of status, since she is in the country legally through travel VISA?
• My brother is currently under F1 VISA, and is thinking of doing OPT or doing his Master's
  • I will apply for his green card ASAP, however is there any way I can choose which processing center my application will go to? California where I reside has 8-10year wait time vs Texas 8-11month wait time. I have family in Texas and therefore I could mail from Texas if that means that it will go to Texas Service Center

Your replies are greatly appreciated!

Well as title states, i'm slightly stressed out.

We just realized my wife (beneficiary) doesn't have original BC with her (left it back in LT), and our interview is tomorrow. She has a notarized copy + Translation. Is that a problem? Or they don't really care about BC's?

I do have my BC and translation, passport etc.

Thanks
