Joining Date Dilemma in UAE: Should It Be March or July 2011 for Mr. XYZ?

Mr. XYZ was on a visit visa in Dubai when a company gave him an appointment letter in March 2011. He started working in March 2011 while still on the visit visa and received payment on the salary date. Due to visa issues faced by the company, Mr. XYZ could not obtain a residence visa before the expiry of his visit visa. Consequently, the company instructed Mr. XYZ to return to his home country, assuring him that they would arrange a residence visa for him. As promised, the company sent him a residence visa in July 2011. The question now arises: should the joining date be considered as March 2011 or July 2011?

Dear Ganesh, please explain the forum clearly. You have maintained the name confidential by terming it as "XYZ," which is wonderful, and we appreciate it. We would like to know the following:

- Was Mr. XYZ paid during his stay in the home country until the company sent him the Residence Visa? On what terms was this period considered? Leave, paid holiday, absent, break, what?
- Were the expenses for traveling to and fro borne by the company?

However, we would like to know, do you deem working or getting employed in a foreign nation on a visit visa to be legal?

Finally:

In any case, the company has accepted and permitted XYZ to work in their organization on a visit visa itself. Then, that date is the exact joining date.

If the company has terminated XYZ or obtained a resignation from him before leaving for the home country, then should it be a re-employment for XYZ, who commences his fresh tenure with the company on a new date?

Can you please be a bit clearer?
