You are a UK citizen in the US for 3 months - no visa is required - When you return home at the end of that period how long will you have to wait before you can return to the US for a further 3 months?
Ask the US embassy for a definitive answer.
When can you start to apply for citizenship after you get your green card through marrying a citizen?
Afterfulfilling the citizen criteria i.e. the citizenship examination , permanent resident requirements, ex citizen requirements and all other rules of which all can be found on the citizenship web site http://www.citizenship.gov.au it can take 1-3 months for the application to be processed and another 1-3 months before you are issued with the citizen certificate through a ceremony all in all say 6 months
Is this a question or answer,lol ! The only way a Jamaican citizen can become a Barbados citizen is through marriage.The Marriage must be valid for 3 years first before citizenship can be given.The Barbados Immigration Department has become tougher in recent months with the implementation of the new immigration rules.
