Question: Can I invest in any state's 529 plan, or am I limited to my own state's plan?
Answer :
529 college savings plans are typically open to residents of any state, while 529 prepaid tuition plans are typically limited to state residents. States that let nonresidents join their 529 college savings plan may have different rules for residents and nonresidents (such as higher annual fees and higher minimum contribution requirements for nonresidents). And keep in mind that if you join a different state's 529 plan (either college savings plan or prepaid tuition plan), you won't enjoy any tax benefits offered by that state--your own state's tax laws would apply.

Note: Investors should consider the investment objectives, risks, charges, and expenses associated with 529 plans before investing. More information about 529 plans is available in each issuer's official statement, which should be read carefully before investing. Also, before investing, consider whether your state offers a 529 plan that provides residents with favorable state tax benefits.
