Just say no!
We need to know what the request was for. Thank you
As per request
Just say no!
No. "May I see your passport, please?" is probably the best way to say it. "For" is not used with "request": you can request someone's passport, or you can request that someone show you his passport. And since requesting is already asking for something, it is redundant to use both "may I" and "request".
Yes, it is correct to say "this is regarding your request" when referring to a specific request or inquiry made by someone. It is a professional and clear way to acknowledge the subject of communication.
Accept friend request.
To request: demander (conjugate as a regular -er verb) A request: une demande, une requête
The correct way to word an invitation is to say, "We request your kind presence at." The invitation does not need to say kind presence to be correct.
is it correct in future form when we say " you are requested to submit the programme" or "you are request to submit the programme"
It will say that your request has been sended, followed by "Send request again" Usually it's not there, but if it's there you know he/she declined it.
as long as you are polite in your request it does not matter if please comes first or after the request. More important that please in added and your tone approproiate
You can say: I comply with your request ( I am obedient to your request or order whatever). In other words, I do exactly whatever you want me to do.
