A. Unfortunately we cannot assist with Visa?s. Our forum has a worldwide reach but the vast majority of users and members are from the USA. This is why we are hosting our first conference in the USA. We are truly sorry if you are from a country which has difficulties in entering the USA but there is absolutely nothing we can do about that. You need to approach the relevant US authorities. We can supply you with a receipt or confirmation once you purchase a ticket. However you may not require a visa. The US offers a very friendly visa waiver program detailed here with a list of countries that participate in the Visa waver program here it's a really simple application process.
