Offshore broker for trading options

This may be a silly question but I was wondering if top offshore brokers like Trader’s Way, etc. offer the ability to trade normal American/European options…what about futures? Is this something normal for brokers that do spot transactions or is it something found elsewhere? I haven’t gone live yet so I don’t know this. I’m just trying to create a solid plan until I’m able to start. By the way this is my first post and I am formulating some pseudocode using a covered option writing strategy so I need the contract and option in the same offshore account. Also, offshore brokers are obviously used for their spectacular leverage (for US residents), among other things, so would this boost in leverage apply for options trading like straddles? For example, if a US broker required $500 margin on CME Globex using SPAN, then would an offshore broker utilizing a 1:1000 ratio for spot require a $25 margin for the same straddle?
