I sent out an application sponsoring my mother's green card (I am a US citizen) for concurrent filing of I-485 and I-130 (as she is in USA on Visitor visa). USCIS sent me an email of acceptance with a receipt number which can track the progress on USCIS web site.
1. Does this receipt number mean that application was valid with all forms were filled in as appropriate?
2. My mother can now stay in the USA till we receive the outcome of the above application?
Thanks folks in advance,
