how much cost of living in arkansas? plz help me.?

Hmm, you are wanting to go into a line of work which has been on the decline in the US for over 50 years. Family farming is increasingly being seen as a line of work from another earlier era, even in states which were historically considered "farm states". Most farming in the USA now involves large corporate entities. But having said that, you might find a niche market--like organic farming--which could be helpful to a family farm. I would see if there is an Arkansas farming organization, or even check out the state government website and see if they have an agriculture section, to learn more about the farming situation in that state. Arkansas is a relatively low cost state in which to live. On the jobs front, it largely depends on where you live in Arkansas. If you are near larger urban areas, you could commute to a job, or look in the northwestern part of the state, near Fayetteville. That area is doing quite well. The general guidance is the closer you get to the Mississippi River the poorer the state gets--fewer jobs, poorer people, etc. Best of luck.

They're not going to let you immigrate to the US with that little money and no job already lined up.
