For example, I have a Wallet and made a request of amount X of BTC to XXX wallet number, If I let it open can I use this request after some years?
i am not sure about this but as long as you save both wallet in safe place, i am sure that in some years later, you can open it and you can use it so you can trying to send your bitcoin from wallet into another wallet. i don't have this experience before so i only say what its in my mind. maybe other member can explain more about this.
