Where to form LLC?

[Carlos O.]

I am planning to see a lawyer within the next week or so. I am definitely planning to create an LLC. However, my issue is that I still haven't settled down on a target market.

For those that have experience with LLCs:

1. Should I wait until I pick my market and form the LLC in that state?

2. Is it difficult to do business in a state other than where the LLC was registered? How much work does it take to do business in another state?

3. Is it more expensive? How much more?

For reference, I'm currently looking at TX and OK, but I live in CA.

Thanks
