Hi Hanna,
how difficult it will be to sponsor your new husband will depend on may things. Some of them could include:
both of your backgrounds - are you both the same religion, cutural background?
how did you meet/decided to marry - was it a tradition "arranged" marriage inline with your culture.
how long have you known each other before marriage
how often/for what lenght of time have you spent together face to face?
Usually if it is a tradition marriage in accordance with cutural and religious norms it takes under 6 month. If like us, you do not fit into these norms you could have a long wait. My suggestion would not to take anything for granted. Proof, proof and more proof that your marriage is legit. Pictures, emails, chats, letters, cards, letters of reference from employeers, friends, family all will help.
Good luck!
