US Immigration from Czech Republic

Hello everyone,

I came to the US as an au pair (J1) in August 2017 and I moved from NY to Atlanta in December 2018. Since I extended my J1 visa for a year my visa was valid until end of August 2019, I applied to change status from J1 to B2, got it approved and applied for an extension which expires on 08/27/2020.

I met my now husband in August 2019, but we weren t in a serious relationship back then. I moved in with him in March 2020 due to COVID-19 and we decided to get married later on. We ended up getting married on 07/07/2020 and have most of the forms ready. My question is, should we send everything before my visa expires on 08/27/2020 or is it ok if we send it later?

The last time I entered the US was December 2018 so I m not worried about entering with an intent since we didn t know each other yet, but I am worried about overstay of my B2 visa. He is a US citizen who is just now filing his taxes so that s why we re running out of time.

Please, let me know your thoughts!
