In almost any career nowadays you must be able to speak English. This goes especially for foreign professional. Business English can make or break your career.
I think in order to ensure that your English is polished and up to date, it may be wise to seek professional help.
Such as ELT’s Business English Course. This would be a fantastic option for executives and professional with basic, intermediate or advanced Business English skills.
What I like about this course is the one-on-one or alternatively, small-group tutoring. This helps a great deal when learning or improving one’s language skills.
English in business is important and you shouldn’t waste any time and start learning rather sooner than later!
