International Travel Policy Required, Pls Help - XLS Download

Hello HR professionals,
I am working with one small software company at Pune - India and few of our employees keep on travelling abroad, particularly to USA & UK. They go on business visit of short duration (below 1 month), medium duration (1 to 6 months) and long duration (more than 6 months) but we don't have any standard "International Travel Policy" for them where their eligibility about their per dium, food, local transport and accommodation eligibility at various locations.
Can you please help me with some sample policy in this regard so that i can design policy for my company.
Your help in this regard will be highly appreciated.
With warm regards

This Policy will cover guidelines on Foreign Travel and Reimbursement of expenses incurred on Foreign Travel.
All expenses incurred on travel shall be claimed in the prescribed Travel Expense Statement accompanied by supporting bills, vouchers etc.
Travel expense statement must be submitted within a week of the employees' return.
For release of Forex, approved itinerary should be forwarded to the accounts department two days prior to the departure.
Reimbursement will cover the following:
#Actual Hotel Expenses
#Transportation Expenses
#Actual reasonable expenses which may include snacks, tips and local expenses.
Kindly do not copy the whole policy as it is.
Hope you can get some help from this.
:) Cheers

Thanks al lot Archna,
This format will is very good and definately it will be useful but still if you can help me with a detailed policy, that would be really great. Surely i will not copy the entire policy but i can take it as baseline.
Regards
