If your question was "can you get a
(spousal) visa if you have hiv?"
[having hiv makes it difficult to become a
resident of the united states --
if you have hiv, you cannot get a visa
unless you can get a waiver.
A waiver might be granted if you are
spouse/parent/child of a us citizen, for
example. You would also have to prove you
can pay for medical treatment, and you
have to show you know enough about hiv not
to infect others.
If you are already in the us legally, you
cannot be deported for getting hiv. But
if you leave the country, you can be kept
from returning -- even if you have a work
permit ("green card").
If you think you might be hiv positive and
want to enter the us permanently, you need
to contact a us immigration lawyer
experienced in hiv matters. For more
information about legal representation,
contact the los angeles gay & lesbian
community services center's legal services
department at +1.213.993.7670 (vox).]

now as for getting a visa regardless of if
you have hiv, yes you can get one if you
are going to marry an american citizen,
but there are certain requirements you
must meet before arriving, and you must
maintain those requirements once you are
here. My brother's wife was a mexican
citizen, and even though she met all the
requirements, it still took about 9 months
for her to get here.
