Hi wafaa28.
It will be easier to marry in Algeria.
By the way, since you have lived in Ireland for more than 5 years, you are now a Permanent Resident. It is not compulsory, but I would recommend that you apply for a Permanent Residence Certificate on form
EU2, as it may help you in the future.
Once married, your husband should apply for an EUTR visa from the nearest Irish mission.
Once he has the visa, he can come to Ireland. In Ireland, he should apply for a "Residence Card of a family member of a Union citizen", on form
EU1.
