To me, to get an regular visitor visa is not easy.
Is easier to get a SUPER VISA (multiple-entry), the insurance is not mandatory if your parents will visit you for less than 6 months.
*You must meet the LOW INCOME CUT-OFF
FOR EXAMPLE: If your Family size is 4 persons (you, your wife and yours parents) ......... the LICO (low income cut-off) must be $41.307
*Invitation letter es mandatory.
