Generally you need to file the claim in the state where you worked and not where you live. In case if you have worked for the state other than Maryland for past 18 months then your claim should be filed against that state. In majority cases, you will be instructed to contact the state where you worked directly, you can communicate with State’s Unemployment Insurance Committee through online. But in some rare cases the Maryland administrative centre will take your claim forward against the state where you worked.
