Respiration controls the amount of carbon dioxide in the blood. If respiration slows, CO2 increases, causing a respiratory acidosis. If respiration quickens or deepens, CO2 decreases, promoting a respiratory alkalosis. This is helpful if there is another process going on that impacts the pH of the blood.
The Affidavit of Support form is a legal contract required by U.S. law between the Petitioner (sponsor) of an immigrant visa applicant(s) and the U.S. government. The sponsor for the visa applicant(s) must establish he or she has certain means to financially support the visa applicant(s), if necessary.
After the petitioner, joint sponsor, and/or household member complete the Affidavit of Support form, he or she should submit supporting financial evidence. This will be submitted to the NVC in Step 6. Additional supporting evidence may be requested by the consular officer at the visa interview.
