After being laid-off from my job in January 2009, my young children and I have "relocated" 3 times while I looked for work, moving from relative to relative. We went from a typical middle-class American existence - I was a hardworking, well-educated executive with a long stable career, a beautiful home, excellent credit, great schools, beloved pets, with wonderful friends and neighbors, and earning well over $100k a year (and even had a million dollar life insurance policy!)
I am now broke, my savings almost completely depleted and I now share a tiny spare room with my 2 kids. I am on the cusp of being a complete financial burden to my relatives ... and I wake up in the middle of the night, every night, in a cold sweat, so ashamed that I wasn't able to prevent this from happening and terrifed at the prospect of the inevitable poverty and hardships my kids are about to face.
First of all, social assistance. Find a job that pays for bills and food, wait for your income tax, use it to make an outsource business that will provide you with capital for a bigger business in the USA. Investments in Mexico are good and closer than other third world countries, such as clean water supplies (about $6k investment) or small business financing (low as 3k total). Hope it helps.
