Confused Principal Architect - What path to take next?

I am a Principal Architect (L67) at Microsoft. I have been an Architect at this or equivalent level for the past 3-4 years at 2 companies. I was an architect at a large startup in a different country. There I was in the top 1% of the engineering ladder. I have also had offers from Amazon (Principal Engineer L7) and Facebook (E6. Has appeared for E7 but was downgraded to E6) both of these outside the US. Microsoft happened to pay better then and I joined Microsoft. Now I am in the US. The reason for giving out this information is to provide context that I have proved myself at this level as a technical architect at more than 1 place and I have received offers for equivalent position in the IC ladder. I have 16 years of experience and my TC currently is ~650K (Stock appreciation included). My TC will likely drop after 2 years. What I am realizing is that its a difficult task to get to the next level (Partner Architect or Senior PE, etc.) as a IC. This probably is my strength. However I have also done enough project management, mentored people and have played an important role in motivating and growing people. I do like that as well. I have not done people management formally, so I don't know how I am at that or whether I will like it. I am also considering moving out of US (to may be Canada or the UK) because of immigration constraints. It would be unfair for my kids if I bring them up here and they have to later move back to my home country. They may not be able to adjust if they spend a lot of time in a developed country. Personally too, I prefer to continue living in US or in one of the developed countries. Considering the above what path should I continue on. IC or Manager. I could think of the following pros and cons IC Pros That’s my strength. I have built distributed systems from scratch. I have a decent understanding of ML to build ML Infra or have conversations with Applied Scientists. I have done decently well for myself as an IC. At this level I have found that there are fewer IC's but lot of Managers/Directors. So it has never been an issue for me to get good scope, get visibility, importance, lesser peers to compete with, etc. Easier to move to a different country as an IC. Cons Generally its difficult to grow as an IC, specially at the next levels. I can probably make Partner if I try (will take some time) but beyond that its even crazy to think about it. It gets more and more difficult to Influence and convince people if you are not a Manager. I hear from my friends that its easier as a Principal or Senior Principal in Amazon, that’s not the case at Microsoft. It was easier at my previous company though. Manager Pros I think its easier to grow at levels beyond where I am. Cons It may be too late for me to become a Manager. If I do become, I will start as a Manager of IC's whereas my peers will all be Manager or Managers. So I will start at a disadvantage there. Team size too will be smaller. Plus I am not sure if my strengths on the technical side will matter anymore. Plus I don’t know how I will perform as a Manager. Moving across teams or companies or Country may be difficult (specially since I might not have enough Manager experience for the level).
