The Trinidad and Tobago government has pledged financial help for the national team ahead of the squad's first ever World Cup campaign.
The Trinidadian Football Federation (TTFF) had asked for £7.26m, with the government offering £4.14m.
The grant, announced by Minister of Sport Roger Boynes, will include bonuses for players and coaching staff.
The team will receive a £1.38m bonus if they progress from Group B, which also includes England, Paraguay and Sweden.
The government grant will help with the cost of training camps in Manchester, Austria and the Czech Republic.
Private business is expected to contribute up to £270,000 while Fifa bonuses will help make up the shortfall.
