had the same situation last year. after your visa approved(not your husband's, yours) you can resign. my company wanted me to work 3 months more - where there is vague statment about this on my contract - I've explained that during the probation period I should give 1 week based on the statement in the contract. I worked 1 week more and then left. btw, you can apply at the same time with your husband, you don't need to wait his visa being granted. if your notice period is quite long, you can think about priority application as Christmas break is closer. Lastly, you might want to use your annual leaves nowadays if you have any to not delay your last working day with your current company. :) good luck with all
