you can raise the service tax but depend upon the services.

There is no liability as the service is performed and received outside India.

There is no need in my view to examine the tyep of service as long as the service is provided and recived outside India. It would be subjected to the laws of that location and India would not have territorial jurisidction.

Thanks Madhukar, I am also of the opinion that services performed and received outside India is not liable to charge service tax. Doubt which created in my mind because engineer professional appointed in India and by an Indian firm. Secondly, One more query is there that whether to deduct TDS from the claim amount by the professional.
