Moses, 25, starred as Nigeria clinched the 2013 Africa Cup of Nations, but his search for consistency on the international scene has been hampered by a series of niggling injuries.
His last Super Eagles appearance was in the 2-0 loss to France at the 2014 World Cup but he insists his commitment to Nigeria should not be questioned.
Unfortunately, I have not been able to play due to injuries but I have an unwavering commitment to Nigeria
"I'm proud of being a Nigerian international and am always committed to playing for my country," Moses told BBC Sport.
"It's the best feeling representing your country and I always want to perform and give 100% for the team.
"Unfortunately, I have not been able to play due to injuries but I have an unwavering commitment to Nigeria."
Moses' debut and last international appearance came under Stephen Keshi, who was fired after the country failed to qualify for the 2015 Nations Cup.
Keshi's successor, Sunday Oliseh, said Moses remains part of his plans despite pulling out of crucial friendlies against DR Congo and Cameroon last October.
Oliseh's comments were a timely boost for fit-again Moses who has played in West Ham's last five matches after recovering from a hamstring injury.
"There is a new manager and the team has been doing well but without me," said Moses, who misses the involvement.
"I'm prepared to give it my all and fight for a place on a regular basis, that's my aim.
"This is football, a competitive stage and I have to fight hard to get in but I don't mind doing that."
Former Crystal Palace and Wigan player Moses joined Chelsea in August 2012, but has spent the past two seasons on loan.
Moses, who also had loan spells at Liverpool in 2013-14 and Stoke last season, moved to West Ham on loan in September 2015 after signing a new four-year deal with his parent club.
At international level, he committed himself to Nigeria despite having represented England at junior levels, up to the Under-21 team.

The exercise follows a number of recent attacks in London and Manchester.
Gardaí responded to three potential scenarios - stabbings, hostage-taking and a car being driven at pedestrians - echoing real-life events in London.
Irish officers are not routinely armed but it has been announced that 10 new armed-support units are being set up.
According to Irish broadcaster RTÉ, the new units will be established in towns and cities outside Dublin to deal with the threat from terrorism and organised crime.
Gardaí also said that it has increased its armed-response capability in Dublin by a third to deal with the threat of gang warfare and potential terrorism.
The head of the force, Garda Commissioner Nóirín O'Sullivan, said 24-hour armed police cover will be available across the Republic of Ireland from the end of the year.
She was speaking in Dublin as her officers practiced their response to dealing with multiple attacks.
Commissioner O'Sullivan added: "We're measuring all the response times so I'm very confident that we have the response capability.
"I'm very confident, as we saw simulated here today, that officers, including our uniform members, know precisely what to do if something does happen."
The training exercise involved members of the Garda Emergency Response Unit and the Armed Support Unit.
Staff from Iarnród Éireann (Irish Rail) also played a part as one of the simulated attacks involved a car being driven at a pedestrian at Spencer Dock rail station.
Two actors, armed with a knife and gun, simulated stabbing and attacking passers-by and commuters at the train station before taking hostages.
In the exercise, Irish police simulated arresting one of the attackers and shooting the other one dead.
The training exercise had been planned since April and followed a series of similar exercises involving other emergency services, including ambulance and fire-fighting staff.
West Ham winger Victor Moses has reiterated his commitment to Nigeria after he was accused by fans and local media in Nigeria of putting club before country.
