itc availability

Hi

we have several marketing executives who used to roam in the market across the nation...

My query is that if they stay in other state of which I do not have the GSTIN no. how can I avail the ITC of CGST+SGST charged by the hotlier.

For example: If Mr.A stays in hotel which is registered under Delhi GSTIN but the company of Mr. A is registered under U.P. GSTIN
And Mr A avails the services of hotel and the hotelier charged Mr.A as CGST+SGST in their tax invoice.
so in that case how can a company avails the credit of that tax under the GST laws.....

Thanks......
