khalli, in our company, the following is written on the salary certificate:

"I shall not hold the Company liable should the Bank lodge a travel ban with the Qatar Immigration Department and/or enforce any other contractual or legal right, remedy and/or sanction against me as a result of my failure to pay or settle any loan, monies and/or charges owed by myself to the Bank under or in connection with the above-mentioned credit card, loan or other credit facilities at any time during or at the end of my employment with the Company;"

so sponsor is not liable.
