The team returned home last week from the Under 17 Beach Handball World Championship in Mauritius, where they defeated Australia twice and the host nation.
American Samoa and Australia represented Oceania against 14 other countries.
Captain Fiapa'ipa'i Fanene said everybody brought their game and they know what needs to be improved on.
"Oh I'm ready (to go to Argentina). I want to take it. Me and my girls have got to work really hard for this since we are the first team (from American Samoa) to be in the Olympics so it's exciting," she said.
