Sure your spouse can apply for a Visit Visa. But very few lucky ones got that. I would say 5% who already had applied thru a spousal sponsorship. So applicant has to prove :-
He/she has intention to return back VERY 1st thing, then show ties back home. Solid employment helps. Properties and income taxes return proofs for last 3 -4 years. Employment stability, any school attendance if that’s applicable, and assets you own, very valuable house with solid proof of present value, children and family, and any other responsibilities that require you to MUST HAVE TO return to your home country. The more you show the better chance you will have to convince the officer. Show as much proof as possible. Also have to show your financial arrangement. If there is no proof of sufficient funds for your visit, unfortunately your application is likely to get refused. Therefore, you should show sufficient funds available for your trip, no matter who’s covering the cost. Don't forget this will be a RETURN TICKET, not one way ticket. So have to spend say $1500 if approved as a visitor, then goes back, comes again another say $1000 ticket..
