Jobs teaching English overseas are plentiful for college graduates with a TESOL certificate which is easy to get.
TESOL is an abbreviation of Teaching English to Speaker of Other Languages.The highest paying jobs are university jobs and go to the people with some teaching experience and a teaching degree. However, there are plenty of jobs for those with a bachelor's degree and a TESOL certificate. There are even some jobs where only a TESOL certificate will suffice. The best jobs are given to teachers with experience and a teaching certification, however there are many good jobs which do not require teaching certification if a TESOL certificate is obtained. The preferred age is between 20 and 30 although 50 years is not too old. Many countries expect you to retire in your 60's so it is harder to get a job at this age. Some countries prefer women to teach young children, but again gender is not always a factor. A country which pays well and has a great demand for teachers is China.
There are government schools, private schools, language schools and corporate training classes in most countries with jobs teaching English overseas. The government schools do not pay as well as the private schools, but the jobs are easier to get. Asia is known for paying higher salaries, but sometimes the cost of living is also higher there than other places.
The schools which provide TESOL certification often can help with job search as well as work visas and other requirements for getting in the country. It is important to research the requirements for a work visa; most countries require a bachelor's degree, although in countries where there is a great demand, this may not be a requirement. There are a few places which do not require a bachelor's degree for jobs teaching English overseas, however, most of the more desirable jobs do.
The easiest way to get a job teaching English overseas would be to take a TESOL certification course from a school which will help you find employment in the country of your choice. There are agencies which will get you a job, but you must be careful that they do not take a big cut of your salary. Before you commit, do your research and make sure you have a constitution which is adventurous and willing to experience some ups and downs as getting used to a new culture, especially when you don't know the language, can initially be difficult.
Most people who take the step to get their TESOL certificate, however, find a great deal of satisfaction in obtaining a job teaching English overseas.
