This is my first post here so I apologize if I've done anything wrong. I've already reviewed GOV.UK and a similar thread from 2016, What are the visa rules for US speakers, at UK conferences, who may be getting paid?, but still have a few questions.
I am a U.S. citizen to the United Kingdom for an upcoming technology conference where I will be speaking. The conference is a for-profit commercial event charging for admission, and while I will not be paid for my speaking engagement, I am receiving my ticket to the conference at no cost for my engagement.
The topic of the conference and my speaking engagement do directly relate to what I do professionally. With that said, I do not intend to do any kind of work for my profession while in the United Kingdom aside from this speaking engagement.
For the most part, I believe I can enter the UK as a Standard Visitor, given the non-commercial unpaid nature of my engagement. However what concerns me is the fact that I will be speaking as an expert in my profession, and the possibility that receiving a ticket to the conference in exchange for speaking may be seen as a form of payment, given that there is a price for admission. In this case it has me questioning if entering the UK for a Permitted Paid Engagement is the more appropriate route. I am aware that being of a non-visa nationality for the UK that I ordinarily do not require a visa to enter for either Standard Visitor or Permitted Paid Engagement, but I would like to be more aware of what this scenario counts as so I can take appropriate action at the time of travel.
