Normally, citizenship carries voting rights, and any other privileges that may be conferred under the constitution of the relevant country. For example, under the Constitution of India the right of freedom of speech is guaranteed only to a citizen. Certain countries may limit ownership property to citizens. In India, the Exchange Control regime is more favourable for citizens of India to own property in the country. If citizenship-based taxation system is followed, it may count as a disadvantage, like the US taxing their citizens even on income earned outside the said country.
