Need Help Writing an Invitation Letter for My Parents' Tourist Visa to Abu Dhabi?

Hi, can someone please help me? I need to write an invitation letter for my parents to visit me in Abu Dhabi. This is the first time I have had to do this, so I am unsure about the correct format. Could someone please provide me with a sample invitation letter for a tourist visa to visit Abu Dhabi? We are processing the visa through Etihad Airways, and they have requested the letter.

Thank you,

Can someone please help me? I need to write an invitation letter for my family to visit me in Abu Dhabi. This is the first time I have had to do one, so I'm not sure how to proceed. Could someone please provide me with the format of an invitation letter for a tourist visa to visit Abu Dhabi?

We are applying for the visa through Indigo Airlines, and they have requested the letter.

Thank you,
