Moving offices later is possible in some situations, but you should not choose an office assuming a transfer will be easy.

Transfers depend on business need, performance, tenure, immigration rules and whether both offices support the move.

A short-term staffing arrangement or project in another geography is also different from a permanent office transfer.

Pick an initial office you would genuinely be willing to stay in, then treat future mobility as upside rather than the plan. For more detail, see the guide to choosing between consulting offers.

For what it's worth, The people and local staffing model mattered more to me than the city ranking.

I would choose an office you would actually be happy to stay in rather than assuming a transfer will be easy later.

I underestimated how much language and work authorization would narrow the realistic office list. That was the part I wish I had understood earlier.
