First H1B Approved for only 1month

Hi Team, we filed H1B application in 2018 April and we received RFE in the same year. we did respond and finally we got H1B approved in the month of December 2019 but only till 31 Jan 2020. interview dates itself takes 2-3 months to schedule interview and couldn’t do anything. The Employer who filed H1 was unable to renew 3yrs. what are my options here please?

You can file H1B extension or H1B transfer.
