Fantastic that UKAPS is going to be represented, and even better that it was Tropica that invited you two.
Interzoo is closed to visitors, but a resourceful person can still go.
In order to go in one has to provide one of the following:
What documents are required as proof of eligibility?
Business registration document which clearly indicates that the company trades in goods exhibited at Interzoo
Extract from the commercial register which clearly indicates that the company trades in goods exhibited at Interzoo
Recent supplier invoices which clearly indicate that the company trades in goods exhibited at Interzoo
Employees can prove their eligibility with written confirmation from their employer on letterheaded paper stating that they are to visit the exhibition on behalf of the company
Students can prove their eligibility with a valid student’s identity card and a valid matriculation certificate
Personal written invitation from an exhibiting company
Admission vouchers supported by business registration document or informative official document
It is pretty straightforward to open a LTD company, and it can be closed afterwards with no penalty, the price I believe is £35.
