if you live anywhere in the West sister, there is no need for a wali, for muslims living as minorities in non-muslim countries have somewhat of a different fiqh [jurisprudence] that applies to them, this fiqh is called the fiqh of minorites and according to this muslims, when faced with difficulties that arise due to the difference of culture etc, can switch to any of the opinions of the four schools or even of past schools that are no longer followed, but whose opinions were based on substantial evidence
no wali is required in the Hanafi school of thought, thus you can adhere to this opinion in your case...
