我已給母親file I-864 when I filed I-130 and I-485.
-How soon USCIS will check my employment?-I don't know and it is possible they may not check it.
-I put some saving & checking on I-864 but very few, will this help?
-If I can't find job by the time USCIS check my mom's case, what will happen and how can I do?-Just wait and no one can predict it. If her I-485 is denied, she can file it again when you have enough money.
-Can I still apply advance porale for my mom at this time? -Yes.
