correlation between parts of a sentence

Hello everyone

I’d like to ask which “without as much as raising any question on national allegiances” refers to in a sentence:

Peggy Levitt claims that people no longer lead lives based on a set of national and cultural norms, in countries with impermeable national borders but belong to two or more societies at the same time and are therefore referred as transnational migrants. Just because one lives and works in a particular country does not prevent that person from maintaining strong homeland ties or belong to religious or political movements that span the globe without as much as raising any question on national allegiances. At this time of cheap transportation and communication costs, emigration no longer signals breaking off ties with the country of origin as it did in the past.

As I understand “without as much as raising any question on national allegiances” implies that nobody asks about one’s nationality, but which this phrase refers to in the sentence?

.
The grammar is a bit off, but it seems to refer to

maintaining strong homeland ties or belonging to religious…globe.
.

Thank you very much, Mister Micawber.

And the grammar is off here:

Use this:

Just because one lives and works in a particular country it should/does not prevent that person from…

or this:

The fact that one lives and works in a particular country does/should not prevent that person from…

or this:

Living and working in a particular country should not prevent that person from…

Thank you very much, Molly.
