Prakash Giri had sex with the teenager in June 2012 at a beach in Dunoon, Argyll.
The 29 year-old - who worked at a hotel in the town - returned to the High Court in Glasgow yesterday after being found guilty earlier this month.
Giri had denied raping the girl or even having sex with her - but his DNA was found on her underwear.
Judge Sean Murphy QC jailed Giri adding he had "taken advantage" of the teenager that night.
In his speech to the jury, prosecutor Richard Goddard said Giri "did not care" the girl was only 14.
