Applying dp10 visa through agents is getting more chance ?

Why has it been rejected? What reason was given? There are some basic requirements that have to be met. One of the major reasons for rejection is the job can be done by a local Malaysian and it is not necessary to hire a foreigner. The second most common reason is lack of experience i.e. fresh grads are not hired.

No greater chance through an Agent - just expensive failure likely. The caveat to this would be if you were being hired by an outsourcer.

Either way, in Malaysia, you don't need to pay anything to get a job. The employer is responsible for all costs.

Note: Agents can be criminals who provide fake immigration documents. This often ends in deportation and a 5 year ban on re-entering Malaysia. It also leads to job scams and exploitation.
