Struggling to get Ireland Visa appointment in UK (holding Indian Passport)

Hi there

I am from India currently residing in the UK. I was applying for short term Ireland Visa to visit my brother in Dublin. I did the Irish short term visit Application. But when I checked in the VFS portal for appointment, it was showing that there are no slots available for any future dates which was to my surprise. Please let me know is there any alternative or way out to do it. I have a function coming in early April to attend. So please give me your valuable suggestion.

Warm Regards
Your friend and well wisher.

Unless you live in Northern Ireland, you have to use VFS.
