Offer by a company and request to pay visa expenses to travel agency

Dear Sir/Ma'am,

I'm a resident of Singapore holding an Indian passport and just a job offer from a company called [--------] in Dubai. In the offer, they've mentioned:

"Newly recruited foreign expatriate employees to join our team are bound to process & obtain 3-year valid U.A.E Residence Visa & Work Permit before joining with our work team on the resumption date. U.A.E Residence Visa and Work Permit are valid only for 3 years (renewable) for employees in Free Zone.

Any Employee who accepts this offer shall contact this Logistics Agency [--------] travel agency & pay all expenses for processing, procurement & acquisition of their UAE Residence Visa & work permit's clearance papers from Ministry of Interior. The employer shall reimburse all expenses upon employee arrival in the UAE."

Is it ok if I pay all the expenses for the UAE Residence Visa/Work permits?

I thought normally Dubai firm shall bear visa expenses.

Thanks
