Overseas Compensation Provided To Employees By Indian IT Companies

Dear All,
Need help to design the overseas compensation policy for our employees traveling abroad for short and long term.
I need help on following things
1) How we will pay the employee if he is traveling for one month or more than that?
Are we going to pay him per diem + actual overseas accommodation
+ Indian salary.
2) In case of long term like more than 6 month what will be the salary components we will be paying him for this period in India and Abroad.
Are we still going to pay him per diem + actual overseas accommodation
+ Indian salary during this long period or per diem + actual overseas accommodation
Pls send me the general company practice followed on this.

Pls share some information about your company policy on overseas travel & compensation.

Dear Sunil,
Would you be deploying your employees at the onsite location? Are they travelling to attend a training? Alternatively, would they join the US Based LLC to work for that duration? It may remain an internal transfer, but the employees are transfered with a new appointment letter. Please do share these administrative details , for us to respond with a suitable compensation structure.
Regards,

Dear Sunil,
Sending you the standard terms and conditions for international assinment this is only on employment visa. Kindly check the attachment.
On business visa means they are on business tour and the host company will look after the housing and repatriation if necessary in additional to this Quality of Living/Location Premium and differ from country to country. They will take the full responsibility during the stay at host country.
Hope this may help you.
Regard's
