Speeding up the employment visa process to avoid overstay fines

Agency will file absconding against a visit visa

Dear Sir/Madam,

I have sponsored my nephew’s visit visa. His visa expired since Nov 25.

The employer already showed me an entry permit of my nephew. But, the agency is still calling me that they will file an absconding case. Can they do that?

As I understand, the visa status has not changed. What would be the impact to all these? If the agency files an absconding case, who will settle the fine?

What happens with the entry permit the employer already filed? What best should be done?

Appreciate your clarification
