1* i f i come to Poznan i can get job?(hotels,restaurants,bar)
2* if i got job i can re pay my bank loan easily how much salary i can get?
3* from Poland i can go any other Europe country?
I've told you time and time again about this issue.
1. No. You can't. Poznań is not so diverse. For an Indian national, your only hope is to find an employer which will want you for your English speaking abilities. But language schools are out, so your only hope is call centres - and there aren't many!
2. 5zl an hour, cash in hand. You might get as much as 7-8zl if you're lucky, but I doubt it as you don't know the Polish language. I know someone that can offer you employment for 5zl an hour plus commission if you're interested? You'd be looking at potentially around 25zl an hour if you're good enough - but he won't be able to offer you more than 5zl an hour guaranteed.
3. No. You'll need a visa for other countries. You might be able to get the C+D visa, but that will require extra proof regarding funds/etc.
