US Immigration from Argentina

Hello everyone! I have a rather simple question, but I can t find definite answers. Most likely I m overthinking it, but I digress.
I have my main job where I get a w2 in January. However, I have the possibility of having a second job. It s for a company where you work for different customers and you get paid cash (think something like Uber). How does one report that income when it s time to file taxes ?

Wondering if any of you that were approved or are pending have this next step status?
mine says

we will prepare your case for officer review

My fianc and I just submitted a K-1 package in July (yes I know going the spouse route is better but we have family and logistical reasons why we couldn t do that).

Can he apply to the visa lottery (he meets the qualifications) while our K-1 is pending? At the rate things are moving it feels like the timelines would be similar and he would have a full green card instead of dealing with AOS once he s here on the K-1.

We have a few red flags that make me panic our K-1 will be denied (large age difference, mostly online relationship due to Covid, government restrictions and a 500 day waiting period for a tourist visa interview, prior marriages) and if it won t affect our K-1 review/approval, I would feel more comfortable if we had both in process even though the lottery is a long shot.

i just don t want to do anything that would add yet another red flag to our file for the K-1.

Hello, we have the same doubt. My husband (petitioner) does not arrive with the minimum income, so we would use sponsors (my mother-in-law and her husband, my husband's stepfather). My in-laws are married and file the taxes together. What forms should we file for them? How do we prove the family union of my husband with his stepfather?

Hello! I got my naturalization interview letter for the first week of November. Way faster than expected. I have a few questions because I need to be prepared. Already have an international trip on Thanksgiving for family reasons to my home country. Let s suppose my interview is successful.
1- How can I find out if ATL office has same day oath? How to request it?

2- In case my oath is scheduled after my trip do I still travel with my GC right?

Trying not to stress with the timeline but hey I m a worrier by nature.

Thank you!
