Can you please help me about chances of getting visiting visa in this situation.
You were bounced (had a visa application denied) for 212(a)(6)(C)(i) Material Misrepresentation/Fraud for self admittedly using fake work experience in your H1B petition. It is a permanent bar which can only be removed via a waiver. Nobody here can help you. It requires the services of a competent reputable and typically expensive immigration attorney, not random guys from the internet which is what we are.
Can I directly apply for visa or Do I need to hire a lawyer for an appeal .
You can do either, your chances of success are almost nil. I would not recommend it unless you're rich and have lots of money to spare. For all intents and purposes barring some change in legislation, your only interaction with the USA for the rest of your life will be from afar.
And how much generally lawyer charge for this case.
Opinion based. Different lawyers bill different amounts.
CONCLUSION
Do not waste the money trying to overturn a permanent ban for wilfull representation/fraud unless you desperately need to return to the USA (because for example you have a wife and children here) or maybe because your life will be meaningless if you do not return to the USA. Canada is a very beautiful country, enjoy it.
