There's a conference happing in Spain in late April for the main software stack for $DAYJOB, to which I'll be heading. As a UK national, that's no issue visa-wise. Work have just OK'd the budget for me to bring one of my team from India to the event too, which means I'll need to help them with getting a Schengen visa.
My company doesn't have any offices or presence in Spain. The costs for the trip (flights, hotels, conference fee, food etc) will be covered (for various reasons) by the UK part of the business for both of us. I believe, therefore, that my Indian colleague needs some sort of invitation letter confirming that all their costs will be covered for them by the company.
I've asked around the office, but the only Schengen visa invitation letters they have are for Indians visiting our Warsaw office, which are written in Polish so not that much help here, especially as I can't read Polish....
Is there any guidance on what I should be putting into the invitation letter? Such as who it needs to be addressed to, what it needs to say about my Indian colleague, what it needs to say about the funding etc?
Otherwise, I'm guessing the letter wants to be printed on company headed paper and signed by someone suitably senior from the UK head office. What about the language though - can it be in English, or do I need to dust off my Spanish dictionary and then invite a Spanish friend over for beer + to help me write it?
