Filing taxes with alien husband with no income

Hello,

 

I am trying to file my taxes for 2019. I got married in August of 2019! My husband came to the US in may of 2019, and we are both staying in the US. He has no worldwide income. I have 2 questions:

 

Should I file Jointly or Seperately? 

I am required to get an ITIN, how should I approach that with my husband having no income!
