UK Standard Visit Visa from Pakistan

[Junaidrai]

Dear Members & Experts,

I hope everyone is keeping well and safe.

I am planning to sponsor a UK Standard Visit Visa application for my Father from Pakistan.

Part of preparation, I am trying to collect information regarding the supporting documents for the subject matter application.

Can someone please provide some guidance on this, I have seen the guidance on UKVI,s web but I am more interested in finding out the actual letters, statements, affidavits etc. which now have become more of a norm or expected by the case workers.

I highly appreciate your kindest help on this matter.

Regards,
Junaid
