Sharjah UAE offer

Hello. Good day!

i just got an offer from a comoany in Sharjah, UAE

offer is: AED 26k per month. would just like to ask if this is a good offer.  i’m single but I heard cost of living in UAE is more expensive compare to other places in GCC.

, I’m a Filipino currently living and working in Singapore. normally, per process I have to take a GAMCA before visa issuance,.. I was informed by the agency though that I just need to go there with visit visa then will just convert it to work visa.. Is this safe?

also, I’m planning to go to UAE to have medical test first before I resign to my current company.. i’m confident that I don’t have any STIs nor a problem with my lungs but just want to make sure before resigning. Will there be a problem if I apply for a visit visa then my agency will be applying again for visit visa in same month? Will it be questioned? how many months is the validity of the medical test conducted in UAE for work visa?

do I need any refernce number/document to conduct visa medical so It will be considered once work visa is processed

thank you so much…
