You would like to participate in a training course Write a letter to your manager about the course and ask for permission In your letter Give details of the course why is it useful for you And how will it benefit your work

Dear Sir,

I am writing this letter to put forward a request to you for an extension of my stay here in the usa. you will be pleased to know that I have completed in-house training with 95% success.
I am grateful to company management for sending me to the usa. I have learned many innovative strategies from inventory management to the retail dispatch of products. However, I could not complete the 15-day on-field training owing to extreme weather conditions. this course imparts practical skills i.e. how to apply strategies in real-world problems. Complimentary to this, the course will also provide free online sessions on how to achieve sustainable development.this is the reason I need your permission to overstay here and complete the training for two reasons. First, It is necessary to observe how strategies are applied. Second, our company will be also benefitted by from their training sessions. also, the company will not issue a certificate of in-house training until I complete it.

I look forward to hearing from you.

Yours sincerely,

Surbhi
