If I apply teaching post in USA, how many years for working visa will be grant? If I am outside USA.?

Question

1. Should I have teaching cert/ training first, or just a bachelor degree is ok when consular consider the case?

2. Is it easy to grant, under what situation we will get higher chance
to get working visa?

Answer 1

You should complete your formal education, including the teaching certificate (although I suppose it's possible to earn this if an employer needs you badly enough, as some inner cities do).
An H1-B visa would allow you to work in the United States for up to 3 years. Review all the details at:

Answer 2

First of all, you need a UNIVERSITY degree in teaching to be able to teach in the USA.

Because teaching children in the United States requires someone proficient in US education law, literature, history, geography, culture, values, and teaching methodologies... you will have to earn your degree here. If you have a 4-year University degree from your home country, you may opt for a 2-year Master's degree in Education here.

Each state has different requirements, as well... involving your coursework background, knowledge of that state's history and education laws/preferred methodology, etc.

Teachers educated in one state, must take additional coursework when transferring state-to-state before receiving full certification in the new state.

The ONLY exception is National Board Certification:

To become Nationally Board Certified, it costs around $2500 total, and the licence is good for 10 years, in all states. It takes a year of accumulating data for your portfolio.

1. Decide what state(s) you may want to live in.

2. Contact the universities in those states that have teaching colleges. Most universities have foreign student support departments, that can guide you regarding student visas, etc.

A student visa may be easier to get than a working visa, anyway.

3. Arrange your funding for your travel, tuition, etc.

Answer 3

Teacher certification in the US varies from state to state, and is often very difficult. If you can get a teaching certificate in your home country, you may be able to apply it or transfer it here. Otherwise, you will need to show completion of a graduate program and student teaching hours.

You may look into private schools, which have less rules about certification. They mostly look at education and experience.
