Immigration help

My wife and I got married November 24, 2018. She was an aerial artist for the circus that we both worked at. At the young age of 13 she traveled here from Argentina to work and better her and her family's life. We had been struggling before the covid, and now her/our industry is shut down. I have a decent job now, but she is struggling to find a decent job due to the fact the her work visa says she is only employable with the circus we worked for. We barely have money for rent, food for us and our dogs, and fuel money to and from work. I know we aren't the only ones affected, but in order for us to do better for ourselves, this is my last hope. The cost of her immigration paperwork so she can get a green card and a proper job is a bit more than we can afford. Honestly, I don't know when we'll be able to afford it. Any help would be greatly appreciated and I have no idea how I would ever be able to repay those that help. Pay it forward will be our thanks, I hope that is enough.
