Dear Customer,
Thanks for joining and trusting us, much appreciated!
We would like to inform you that if you applied to visa and was rejected, then yes you can apply again but we advise you to find out the rejection reasons to avoid that again. Note that grating visa decision depends on the embassy and no one can force them to do other things. It is clear from your question that you didn’t provide enough guarantees to return. So we advise you to appeal against the rejection during 30 days of the rejection to find out the reasons and you can convince them that you will return if you have residence in UAE, so you can provide letter from your work to prove that you are still working and clarify the salary. So the court of the embassy may edit the decision and grant you visa.
Note that if you were rejected even after appeal, then you can’t apply for visa again unless after 3 months\90 days and you have to avoid the rejection reasons.
If you have another question related with our section, feel free to ask us and we will answer with pleasure.

Dear Customer,
Welcome again!
You can go to the Consulate or the embassy and get an appeal form and fill it out providing the reasons of you objection to the rejection. It does not require a lawyer, and you can know the reasons personally and then fill out the form of appeal and submit it taking into consideration that it has not passed thirty days of rejection.
Accept our respect and appreciation.
Kind Regards,
