There is insurance but it applies on death only. So you have to find a job. If the company where you find already is in approved list, no need to worry. Just present the offer letter & a letter from the company ( new) that your visa is under process. On receipt of letter, please approach your branch. If you don't find a suitable job & want travel ban so that you can find a suitable job, please make sure that you give guarantee cheques against your loan to bank so they will do the rest. If you already given cheque & needs a clearance letter without payment of money, you need a good guarantor!!!
