Thanks for your response.
Well it is like self-employed job.I doubt, that I can qualify somehow for it as I am a non-EU worker.
For me it seems to be, that I need to wait for my long residence status.
There is no legal way I can register at the moment with Revenue.
But I wonder, will I get in troubles with Revenue office for my bank transactions. I hope my immigration status will be sorted within 2-3 months. Do they(banks) have some special limits for transactions (weekly,monthly etc.) after which they must to report to Revenue or something like that.
Thanks.
