Are you of Dominican descent? Not clear from your description of yourself.
Do you speak fluent Spanish?
Wages here are lower than where you live and, if you come here looking for work, you will be in competition with Dominicans. The salary you will be offered, if hired, will likely look very low to you, but might sound pretty good to a Dominican.
If you have special skills, etc., you can negotiate for a higher pay. But since you are looking for an administrative assistant job, you are likely to be paid on the local pay scale.
