Hi teacher, you work for 2 ESL companies and I want to do the same method you are doing. My question: will the 2nd ESL company (I will apply to ) ask me for clearance or contract of employment (COE)or contract of service (COS)? 2nd question: During interview for 2nd company, if they ask if I am currently employed for another ESL, Should I say "Yes"? Any advice helps po. thank you again!
