The US entered the war with their declaration on 6 April, 1917. The war technically ended (the armistice) on November 11, 1918. They were at war for one year, six months and five days.
The US congress declared war on Germany on April 6, 1917. The United States was never formally a member of the Allies but became a self-styled "Associated Power". The US remained a participant in the war until the Armistice was singed on November 11, 1918. The final peace treaty, the Treaty of Versailles, was signed on June 28, 1919, but was never ratified by the US congress.

The United States declared war on Germany on April 6, 1917. They actively fought until the Armistice that went into effect on November 11, 1918. Thus the total amount of time that the US was in the war was about 1 year, 7 months, and 6 days (or simply 585 days).

However, U.S. troops were not in Europe (France) straight away. Gen. John J. Pershing (U.S. Expeditionary Forces leader) didn't arrive in Bologne-sur-Mer, France until 13 June 1917 and that was with a scant 190 American soldiers.

The first major engagement wasn't until after March 1918. It is estimated that actual combat length for the U.S. is between six and eight months.

There was no such thing as a tour of duty. You went to the front and stayed there until you were killed, wounded, cracked up, or the war was won. If you were wounded, but able to go back, you did. In all armies a handful made it all the way through, start to finish. Many fought for three years. US troops were really heavily engaged for only the last six months.
