Is this sentence appropriate?

Kak Serwan Is this sentence appropriate?

Appropriate to what? Who are you going to say this to?

Please I asked doesn't go together very well. Are you just asking for a reference? Or are you trying to scold someone politely for not giving you a reference? It sounds a little like the latter.

CJ

I want to ask my manager to give me a reference letter for another job opportunity because my current work will be finished.

Thank you in advance.

You can use this: Could you please provide a reference letter for me?

CJ

Thank you CalifJim.
