Visa/Sponsorship transfer Procedures during Probation period??

Dear brothers, Asalaam Alyekum

Just two weeks ago i came to Riyadh on Company Sponsored work visa and from 1-2day am not able to adjust in this dry hot climate. I am facing D-hydration with dust allergy which is causing me breathing with nasal infection problem here. My question is CAN I ASK MY CURRENT Employer for Sponsorship Transfer during probation period to other Employer in Eastern Provice like Jubail Damman, khobar As i have earlier spent 4 yrs at Jubail and was fine with no health issues.

Kindly advice your suggestions. For this your kind act i will be highly obliged of yours.

Jazak Allah

Khalid

i Have another question!
what is the minimum age for transfer of sponsorship? is there any provision for changing sponsorship if the sponsor(father) has passed away? my brother is 18 years old and he wants to transfer the sponsorship to my fathers employer who is willing to coordinate along. is it possible? if not is there any other possible procedure for doing the above?
would be really thankful for your information.
