Help me get a work visa!

Since i was seven years old I have dreamed of being a teacher. I love every part of teaching and have been working with my preferred age group of three to five year old children for six years now. I have a bachelors degree in early childhood education and I would love to further my education so that one day I may be able to write a book about the development needs of 21st century children. The US does not treat teachers in primary levels well at all and I am tired of working two part time jobs just to survive and pay for my school supplies. Please help me aspire to be the best teacher I can be and live a better life.
