Hi Dear Expats!
I wanted to get advice about my RNM situation. I really think that the data on it is really very confused. For this, I need to explain the history聽

;
I got the permanent residence card, RNE based on marriage in early 2016. (Using RNE for previous version and RNM for the new one, just to make things clear). I prepared all other documents and hence started working as "Trabalho registrado na carteira".
I worked for quite some time, then I decided to continue my studies in the field of my profession (earth sciences). I passed the University entrance exams (both language and subject-specific) for graduate studies and got admitted into Ph.D聽

. I left my job (canceled contract on carteira de trabalho) to continue with my research.
I and my wife stayed together until 2019 and got divorced in early 2019. I didn't know about the possible cancellation of my permanent residence. But later on, I discovered that the PF had canceled my permanent RNE

. I went to my home country and applied for a student visa based on my Ph.D. studies. When I applied for a visa, PF called my ex-wife to know my conduct and it went smooth since we had a friendly divorce. The cancellation of Permanent residence is really ambiguous and I went to talk to the authorities with a lawyer, they simply answered that divorce canceled my permanent status. (This happens to few people, I was not lucky enough )
I came back and applied for a temporary RNM. Got the temporary RNM with the following weird deadlines;
Validade de 1 ano (correct for temporary RNM)
Classificacao: temporaria (correct for temporary RNM)
Prazo de residencia: 01-01-2025 (wrong for temporary RNM, right for previous nine years` RNE)聽

I applied for a change of "prazo de residencia" to be the same as validity but they couldn't change in the local office. The RNM came with the same error. The PF officer told me to wait as they will contact PF聽 in Brasilia to change. (They couldn't give me the card because it was really wrong).
Once again they applied through Brasilia and this time the "prazo de residencia came as "Indeterminado". They gave me the card saying that it was correct.
I searched and came to know that "indeterminado" is used for those who have classificacao "Residente" (Previous permanent RNE).
So now my RNM card has the following data:
Validade de 1 ano (correct for temporary RNM)
Classificacao: temporaria (correct for temporary RNM)
Prazo de residencia: Indeterminado ( still wrong for temporary RNM, right for previous nine years` RNE)聽

I know that I need to renew my RNM every year but still my classification is "indeterminado".
I talked to some lawyers and every one had different opinion.
Some said that I am a temporary resident and that`s it.聽

Others said that I could apply for naturalization but that still seems strange to me since the RNM classification is temporary.

I was thinking of using the link below to renew my RNM this year. I am here for more than 5 years, but still what I dpn't understand is 4 years` condition. I am unsure about whether it is total time in the country or total married time?聽

Regarding the status of my "Carteira de trabalho", although I am not registered for the current work but it seems still valid as I saw through the app. I wanted to know, If I am temporary and still with these strange dates, could I use my "Carteira de trabalho" for work in the future? Although I am not looking for work now.
Isn't it very confused? did it happen to anyone? What is your advice in the above case. (Sorry for long story, but still it is very much shortened)
Thanks and stay safe.
Cheers,
Ben
