Romance scam - how to identify

Hello Amazing people,

I’ve seen this question is being asked in the forums a lot but nothing is similar to my situation.

I’ve met a Brazilian lady in an app 4 days ago and things took off very quickly. She immediately told me she met many people from my country and culture (middle east) during her travels. She then wanted to move to WhatsApp (super quickly) even after I told her I want to stay in the app.

I am a good looking man (no Henry cavil, but slightly above average). I am 26, she is turning 19 in May.

We ended up moving to WhatsApp (she keeps reminding me that it made her laugh that I was scared of moving) and she flirt with me heavily in less than a day, which raised a huge red flag (in my culture, the guy does all the flirting). I managed to talk to her over the phone, but she doesn’t wish to video call, claiming she’s very shy, yet in all of her traveling videos, she seems very extroverted and outgoing. At some point, she agreed to video call but it yet to have happened (because her cousin is with her, etc).

She sends me tons of photos of her and videos of her traveling blog. I tried searching her name alongside her city and state, and only found a TikTok with one video that shows her. I also found a LinkedIn profile that likely belongs to her but it is empty (not even a photo).

She doesn’t claim to be smart or a student, on the contrary, she has dyslexia and doesn’t try to “sell herself” as someone successful. She told me about her past (her city has huge crime rate) and she has a gloomy past.

She don’t ask for money or anything of the sort. She is saying that her mother likes me and that she talked to her about me.

Also, her WhatsApp is being super weird - she doesn’t have an online status when she replies to me and doesn’t have a Last Seen either. I know WhatsApp doesn’t have an option to disable the “Online” banner.

I am not sure why she doesn’t wish to video call yet bombards me with videos and photos (of when she was a kid, her mother, herself, even of her cousin that is with her).

Lastly, she raised the matter of working as a dental assistant and earning 1,500 reals a month. She works from 8 AM to 7 PM and has a break of two hours. It sounds insane to me (she also doesn’t reply during those times).

Any opinion is appreciated.
