I am currently working on a critical skills employment permit, I am married and have a daughter, my wife and daughter were issued dependent visas November last year. Now I would like to apply for a visit visa for my parents to come here to visit us here in Ireland, both of them haven't worked in a conventional way, like my father was self employed as farmer and never had a bank account. What would be the best route to follow. I know about stamp 0, but I don't think that I would be able to show that I can sponsor both of my parents, and that is I also think about long term visa, rather than a visit.
Why not the short stay 'C' visit (tourist) visa? which would allow them a stay in Ireland for up to 90 days? They can include in the applications a letter from you that says that you will host them throughout their stay and cover their costs.
If you (the family member in Ireland) are funding their trip, in whole or in part, you would have to include your financial details (bank statement, payslips, P60), and your employer letter, along with their own financial details. Underwriting their travels does not relieve them of the obligation to disclose their own finances; indeed, it may raise the bar. They should take care to offer proof of their home country obligations and that they will return there.
Stamp 0 may be an alternative, as it does take into consideration older dependent family members. It is not for long term residence or citizenship but, rather, for those whom INIS approves entry for a limited and specific stay.
