How much income and time if at all immediately does a U.S. citizen needs to marry a Chinese H1b Visa female and extend her stay?

In general, when sponsoring a foreign national for a green card base don marriage, U.S. immigration will want to confirm: 1)  The relationship/marriage is real and legitimate and not a sham marriage for immigration purposes; 2)  The foreign national does not have any prior criminal issues that would affect green card eligibility 3)  The foreign national does not have any prior immigration problems that would affect green card eligibility 4)  The U.S. citizen spouse can meet the I-864 affidavit of requirements If you have been working for only a month, that may not be enough time to prove you meet the affidavit of support requirements.  depending on how long you have been married/living together, your foreign national spouse may be able to use her income for this purpose or you may need a co-sponsor.
