it is extremely diffcult for husband to get sponsored by his wife. First, it depends on the company status. Then, wife should be on the senior level in the company, her salary should meet ceratin requirements. even with all this, such cases are entire prerogative of the authorities, it's not resolved by default, but rather as an exception. You will NEVER know the outcome of your application unless you apply. Every case is different.
and it's not really new. it is existing few years, but rather rarely used.
