As far as i know, wala naman magiging problema dun, they require lang the police clearance from that country para macheck if you have criminal records or anything.Other than that, wala naman din akong alam na nakakaaffect yung visa as OFW sa applications natin sa CEM.
Worst case scenario, if ever they ask for exit visa or something, you can always attach an explanation letter as to why walang exit visa and re entry visa lang ang binibigay, you can even ask your employer for a letter to support this and include in your explanation letter if the issue arises.
