Germany's Defence Minister Boris Pistorius says men of military age in Germany do not need to report lengthy stays abroad.
His statement comes after a controversy broke out over the possible consequences of a new law which re-introduced military service in Germany.
The Military Service Modernisation Act, which came into force on 1 January, aims to boost defences following threats from Russia in the aftermath of its full-scale invasion of Ukraine.
In a statement sent to the BBC earlier in April a defence ministry spokesman confirmed that males aged 17 and older were required to obtain prior approval for stays abroad lasting longer than three months.
The requirement to obtain permission had gone largely unnoticed until it was reported by a German newspaper last week.
