Thank you so much for your question my friend and congratulations on your marriage.
It will really help you if you get a ITIN for your husband if he does not have a permanent visa, so you can file married filing jointly. It will give you a higher benefit on your taxes because the standard deduction is higher as Married Filing Jointly. If he has a permanent visa it is recommended to get his social security card not ITIN.
To get ITIN, you need to fill form W7 when you file your tax return.
Form W7 - https://www.irs.gov/pub/irs-pdf/fw7.pdf
Instructions on Form W7 - https://www.irs.gov/pub/irs-pdf/iw7.pdf
To get a social security card go to https://www.ssa.gov/
I hope this answer your questions.
Thank you so much
Martha
