Finn "karrigan" Andersen has had his ESTA deined and will not be able to enter the United States to play in Astralis' ELEAGUE Week 3 matches.

karrigan tweeted that due to ESTA restrictions, his recent visit to Iran prevents him from entering the US. However, he later tweeted that because he entered Iran on a 72-hour business visa he may be eligible for the ESTA.

No travel fo @EL tonight, my esta denied. New rules from 1st april - you cant travel to US on ESTA if you have been in Iran (within 5 years) — Finn Andersen (@karriganCSGO) June 5, 2016

@Thooorin Now I read online "business-relations" in Iran should be "okay", my visa was "72-hours business visa" We will see tomorrow. — Finn Andersen (@karriganCSGO) June 5, 2016

The ESTA (Electronic System for Travel Authorization) is a system designed determine the eligibility of people applying to the US Visa Waiver Program, allowing them to enter the country without a visa for up to 90 days. In January, the US State Department added a restriction to the ESTA under the Visa Waiver Program Improvement and Terrorist Travel Prevention Act of 2015 that prevents use of the VWP for anyone who has entered Iran, Iraq, Sudan or Syra after March 1, 2011.

There is a clause in the act that allows the Secretary of Homeland Security to waive these restrictions for anyone deemed to have entered Iran for " legitimate business-related purposes."

Astralis' Jakob L. Kristensen has since tweeted that they will provide an update on the situation on Monday after speaking to the US embassy.

We will provide an update tomorrow on the situation with @karriganCSGO once we have talked to the Embassy! @astralisgg — Jakob L. Kristensen (@ASTJakobLK) June 5, 2016

Astralis are set to play in Group C of ELEAGUE with Counter Logic Gaming, SK Gaming and NRG Esports from June 14-17.
