Hi,

Kindly read your contract in 1st case. You can submit your resignation at your own willings and resign from the company during probation period by giving 3 days notice. Incase your probation period is just 3 months then by default you are confirmed employee of the organisation.

In the above case you need to provide to company 1 month notice of resignation or 1 month salary pay.

Incase you contract says there will be any recruitment charges then you will also have to bear that pro rata basis.

Since you have not completed minimum 1 year of your service you will not be entittled for any benefits. Ticket you will have to arrange to go back to your country

Think wisely....
