Saudi visa stamping problem

Dear Friends,

  I got one offer in saudi arabia as mechanical engineer visa category also same. But before i was working in saudi arabia same as mechanical engineer position but visa category is labour visa as electrician. whether the new visa as mechanical engineer is stamping on my passport or not? During visa stamping time saudi embassy will make any problem? Because new visa is engineer visa old visa is electrician visa...

Dear 100% no problem , my brother did so.
No worried n best of luck
