http://onlineservices.immigration.go...nual/35058.htm It looks as though you would have to declare this conviction, and would be told to write a letter asking for a character waiver. (Use Search and find old threads on the forum about that.) The same is true for applying for a work visa, though the heading there says 'Residence'.
1. Am I eligible to get work visa for SMC?
2. Am I eligible to get residense visa after 1 year I got work visa?
Your two questions don't seem to make sense. Applying under SMC is an application for Residence, not a work visa. And if you get a Work To Residence visa (because of a job offer from an accredited employer), then you have to work for TWO years before you can apply for the Residence From Work visa.
