The tie with Uruguay, played over two legs, for the right to take up a place in Pool B in the tournament and qualify as Americas B, was locked at 27-27 following the first leg in Montevideo.
Uruguay took a 13-3 lead into the break, but the double from the Suniula brothers saw the USA Eagles home 32-13 to triumph 59-40 on aggregate.
Earlier in March, it was confirmed that Georgia had qualified for the competition and would appear at Kingsholm, and it's exciting to confirm that the USA Eagles will also be playing in GL1 against Asia 1.
That final place is still to be decided following the completion of the Asia Five Nations tournament, with Japan the heavy favourites.
With the tournament now less than 18 months away, the confirmed fixtures to be played at Kingsholm Stadium are as follows;
Saturday 19th September - 12:00 - Pool C - Tonga v Georgia
Wednesday 23rd September - 14:30 - Pool B - Scotland v Asia 1
Friday 25th September - 17:00 - Pool C - Argentina v Georgia
Sunday 11th October - 20:00 - Pool B - USA v Asia 1
