Heh, 22, was born in a refugee camp on the Thailand-Myanmar border and was resettled in the UK in 2006.
He signed for Sheffield United in 2014, and spent a couple of months on-loan at Stocksbridge back then.
A loan spell at Scottish side Dumbarton followed, before he moved to Eastern Europe, first with Lithunian side DFK Dainava and then Latvian sides FK Jelgava and FK Jonava.
His international clearance is expected in time to face Pontefract Collieries in the EVO-STIK League East Division on Saturday.
