Your mother in law could come to the US on a visitor visa and then sometime after arrival your wife could file an I-130 for her mother to become a permanent resident. Consulting with an immigration attorney id s good idea. There are many in the Atlanta area.

Tough scenario if your wife is not yet a citizen. BTW, you don't need $500K for an entrepreneurial visa. You can get an E-2 for Polish citizens for much lower than $500K (ex: $60k has been approved for Polish business). Thus, provided your mother-in-law is at all entrepreneurial/ managerial and has about $60-100K in cash to open a US business, that might be a way. Humanitarian parole might also be another option but it is not long-term (might be granted solely for the duration of her medical emergency). I would suggest consulting a lawyer since the viability of these options is fact-specific.
