We have had my Mum/Dad in laws over 5 times over 20 odd years and never had a problem with the visa`s. Showed bank statements, no payslips as Mum in law not working and Dad in law Jeepney driver, invitation letter including the promise to cover all expenses, apply for 6 month visa.
They have good reason to return home, such as rest of family being there, grandchildren etc.
They never stay the full 6 months as they get fed up with the relations over here wanting them to visit and stay, and then my sister in law over here also starts to get a bit jealous if they say they want to stay with us, so rather then say no to anyone they go home.Sad really.
So just put in a confident application , and good luck.
