Is it sinful to pray all prayers at home?

I live in a Sunni majority country and the nearest Shia mosque is more than 2 km away so going their thrice a day regularly is not feasible.

Praying in Sunni mosque in the Shia way might land me in trouble.

I'm thinking of moving to USA, and the place Im planning of moving to is also sunni dominated and has no Shia mosque.

Will it be sinful to pray at home? And also will it be sinful to pray Zuhr instead of Jummah as Non Muslim countries dont give off on Friday? Will my migration be sinful even if I pray 5 times regularly at home?
