You have kinda good English, you only need to keep practicing conversations. Your English level is pretty good. Good luck and I hope you achieve your goals in USA. I would advise you to enrich your vocabulary by studying variations. Variations is the study of the different ways to the say the same thing by using some colloquialisms of a specific region so that you'll find many options when creating a song since it will help you to finde the best words to follow the rhythm you want to transmit throughout the song you're singing. The study of some phrasal verbs is also going to help a lot when you need to find a word with different pronunciation but with the same meaning to put in your songs and in this was you won't lose the Rhyme of Song. If you need anything else let me know. In bocca al lupo 😊 lo stai facendo bene

Your speech is very understandable but it is way too slow and monotonous. You need more melody and articulation.
