Question:
I made my first colony in Brasil and I occupied land of some "Tapuia" Indians neighboring to my colony. But in peace negotiations I see only "Force migration". I cannot annex them or claim the province. What is the problem? Perhaps I have wrong casus belli. It seems I'm unable to get "conquest" casus belli against Indians?
- Do I need research some tech/idea for that?
- Maybe I need create some "core" in Americas first? How can I do that? Do I need to grow the colony to "City" first?
background (not necessary to read):
I play play Bohemia at year 1530 – it took me long time to get to the sea. I started to think about colonization only after I became HRE Emperor and annexed Burgundy (including Holland). I terribly lag behind Portugal, Castil, England and even France in colonization. But my army is strongest in Europe (4000 man stronger than France and Ottomans).
In general I find it very hard to grow colonies (it is extremely slow, all other nations grow colonies much faster). I was thinking that by conquest of Indian lands can compensate my lack of exploration/expansion ideas, using strength of my army.
I have researched only "exploration" idea to "Quest for New world" stage. I don't have "expansion idea" yet. I have barely colonial reach to touch America (just Antilles + apex of Brasil).
Before I finished "Offensive" ideas, and picked "Influence" (which I regret, since I would prefer colonization over influence, but that was before I claimed Holland).

If you're using the "Force Migration" Casus Belli, you cannot take any territory, as discussed on this reddit link.
To take territory from natives, you need to fabricate claims and declare war with a conquest casus belli (requires a core or completed exploration ideas), or manufacture any other CB that lets you take territory (or you can declare with no CB, but that has strong consequences).
You can get a territorial core when your colony becomes a full city. If you have I believe the El Dorado DLC, then your Brazilian colonies will form a colonial nation when you have 5 cities in the region, at which point they'll start expanding on their own through colonization and conquest (though they'll be pretty slow until they're big enough to have a strong income).
