A 16-strong squad belatedly received their immigration documents over 11,000 kilometres away at the United States embassy in Yerevan, Armenia. 

It is not yet clear if they will be able to arrive in the US city in time for the start of competition.

This comes after a series of delays in receiving their visas following the travel restrictions imposed on citizens from Iran and six other Muslim majority countries in an executive order signed on January 27 by US President Donald Trump.

After initial delays, Iran Archery Federation President Mohammad Ali Shojaei announced in a message posted on the website of the national governing body earlier this week that requests for just five of the 16 had been successful.

He then clarified yesterday that all 16 had been issued.

It was confirmed this morning that they have now been collected. 

"We have received information from the Embassy in Yerevan that they have picked up their visas this early morning," World Archery added to insidethegames.

"So now it is a question of getting on a plane to get them there on time."

The Iranian squad includes male and female athletes across senior, junior and youth age group categories along with several coaches.

Archery is one the most popular sports in Iran.

Zahra Nemati became the first Iranian woman to win a gold medal at either the Olympic or Paralympic Games when she climbed the women’s individual recurve W1/W2 podium at the 2012 edition of the latter in London. 

The 31-year-old, who is not competing in Las Vegas, participated at both Games last year in Rio de Janeiro and carried the Iranian flag at the Opening Ceremony of the Olympics.

It comes after Iranian Foreign Minister Javed Zarif announced on Twitter last week that a US wrestling team will be allowed to compete at a Freestyle World Cup on February 16 and 17 in Kermanshah after retaliatory restrictions were placed on US immigration there.

Sports bodies including the International Olympic Committee (IOC) have called for all athletes to be able to compete at events in America.

This is despite restrictions in Iran and other Muslim countries on allowing Israeli athletes to compete.

Fencer Ibtihaj Muhammad, a Rio 2016 bronze medallist who became the first Muslim American to compete wearing a hijab at the Brazilian Games, has also claimed this week that she was detained while recently trying to enter the US.

"I personally was held at customs for two hours just a few weeks ago - I don't know why," the 31-year-old, who was born and raised in New Jersey, told website Popsugar.

Archery qualification is due to take place in the US city tomorrow before finals are held on Saturday (February 11).

Brady Ellison, the three-time Olympic medallist, will lead the home team as he chases a fourth indoor World Cup Final title in the men's recurve division.

The World Cup Finals is taking place alongside the Las Vegas Shoot mass participation event at which over 3,000 are expected to compete.
