I work with both CMU and Mae Jo in the field of environmental engineering. I am not employed there but involved in joint projects. Best you visit both and discuss they could possibly offer you a position. Salaries are very low but at least it’s a possible way in.
Sorry but many of the comments are rubbish. It’s not the number of times. It’s the pattern and abuse. Some people like me have entered visa exempt more than 12 times in a year. but each time I leave the country for 7-10 days. Then there are people who come max out and get an extension then leave for a day and repeat. And repeat again. Then you could have a problem
