Rights of the employee upon termination without a valid reason

Sir,

What are my rights (terminal benefits) when terminated from employment as the company does not require my service?

There are no negative records in my service period and the company is now trying to reduce the cost as they have fewer jobs than expected.

I have worked for 2 years and 4 months (stamped second visa).

How will it be if termination with immediate effect and/or immediate termination with the salary in lieu of one-month notice?
